Best quality keybed

Hi all,
 
who makes the best quality keybeds?
 
I'm looking for a synth action 61 key with aftertouch and I want a high quality keyboard with a quiet action after a disasterous encounter with a Kronos X61 recently ...yesterday in fact, it's now on its way back to the supplier.
 
Looking to spend up to £1600 I'll also consider much cheaper keyboard controllers if they have a good solid keybed, also looking for analogue and digital synth recommendations if they have excellent keys.

I like fatar beds, but are you talking piano?

The PC3K/6 or PC3K/7 would be a good choice. They are all the same synth engine so no difference there only the keyboard length and action the PC3K/8 action is weighted.
 
Kore 64 doubles its already extended capacity. There is a rather larger library of free sounds on the site that give huge electric piano options, synths and the Take 6 vocal ensemble. That is all free. With everything installed you are up to 4200 patches and over. It has a built in General Midi synth too. Not to mention the virtual organ and VA-1 analog virtual synth. There is another very nice library available from Sweetwater apparently which adds to it further. (in the form of a USB stick which you just plug in the back and it reads it) It connects to a computer via USB as well. (Midi of course and SPDIF) 
 
The PC3K can read the pre existing K2000 library. This is very good and often the patches sound better in the PC3K. It sounds better than all previous Kurzweils too I am sure of it.
 
Expression wise it is loaded everywhere. Pitch and mod wheel and switch programmable. After touch is very nice to use. The 10 sliders on the front are also programmed heavily into the patch and enable very fast editing effects included. I have just put the ribbon controller on and it too is excellent. It can be one large one or 3 smaller ones. It can do a lot more than pitch effects of course. The arpeggiator is killer too and way too much fun. You can plug a breath controller directly into it as well and control internal sounds and send over midi too. The browser is amazing and you can find sounds in seconds. The setup mode turns it into a super controller and makes very complex setups instantly recall capable.
 
VAST is huge and extended in this version. The latest OS has added a raft of features. Up to 32 layers per note means very complex programming. The editor is essential and makes it all 10 times easier. It is a synth powerhouse. There is nothing modest about it. You could do everything a Roland Jupiter 80 can do I am sure of it. The touch sensitivity on the sounds and way they change with your playing is jaw dropping. (when it is programmed in)
 
It sounds incredible, better in my opinion than the other major synth brands. The sounds record so well and stand up so easily in a complex mix even with no processing involved. With other synths in a recording situation I am often battling it out with the sound trying to make it decent, using many plugins and stuff. Not so with the Kurzweil. It has a big warm a kind fuzzy feeling type of sound. It is clear and cuts through even at low volume in your mix. It pumps out a serious +4 dBu or louder and is dead silent too in terms of background noise.

I just got an Akai MPK61 and the build quality is excellent.  All the control knobs and sliders are excellent.  The keybed feel is a bit stiff, which I happen to like but it's a personal preference.  I just bought it on sale from amazon.com for $399.  Amazing deal.
 
Only negative thing I'd say about this board is that it tends to play loud (high velocity) better than soft and expressive.  But there is an editable response curve which mitigates this quite a bit.

I am referring to Kurzweil PC3K models too which are the most recent. Previous models may not perform as well. They say they have refined things a little more. I found the opposite to be true in terms of Kurzweil response. I was a little concerned as to how the action might be on the 61 note model but to my surprise it is really great. It has some firmness to the action and you can get into it. I also found it to be super fast responding. Almost too fast. No sluggish response at all.
 
But these synth actions can sometimes be faster than the 88 note weighted action where the Kurzweil might be sluggish to some extent. The keyboard player in the tribute band I am playing bought a Korg stage piano for its nicest action and pretty decent acoustic piano sound.
 
The 61 note Kurzweil action is lightening fast to respond as soon as you touch a key. It feels like zero latency for playing purposes. I like it a lot.
