to komplete or not komplete, i wonder

Even if you didn't think all the modules are "necessary", you would probably pay close to Komplete's price with single buys for the stuff you would use ...but you would probably get less than 50% of what Komplete has.
Granted some would be (arguably) better, but you would not have as many options/choices. 
 
Definitely worth it, but plan to spend all afternoon loading everything in!

I think Komplete is pretty great, particularly since Kontakt is kinda the thing for samples. Well, this gets you Kontakt plus a bunch o' extras so it is a great way to go.
 
I don't much care for action or session strings, but having Kontakt I could, and did, get Kirk Hunter Concert Strings 2 which I like a whole lot.

I'm not saying it is not a good buy but I don't really use the majority of the things that came in Komplete and probably never will.  Kontakt is my main NI tool and I had already purchased the packages that I wanted so I didn't gain a lot except less free drive space.
 
I purchased K9 because of the killer upgrade sale for $199 a while back but will not be upgrading to K10.

I just got the email that Komplete 10 will ship 10/1. Seriously looking it over. I have Komplete 9 but not ultimate. Is it worth it? No question...I'm leaning the same way as strikingly handsome. Since I'm looking at a computer upgrade soon I don't mind waiting for a sale, by then I should have another machine up and running. 
 
Komplete takes some work to learn, especially if you dig deep into Reaktor...but as a song building tool I think the set of tools is amazing and worth every penny.I don't think it has any equal competition, all things considered.

You won't regret it Jarsve. And, you get the Rick bass

I ordered mine today. Komplete 10 U that is. Don't care about the keyboard. Its cool and nice, but for that price is to high.
How large hard drive  do I need? Is it a point to have it on a SSD?

Well you do not NEED to have Komplete Ultimate on a SSD hard drive.  many of the Kontakt sample libraries will benefit from being on a SSD hard drive but Massive Synth won't or FM8.
 
I have all of Komplete 9 Ultimate on a 7200 RPM SATA drive and have no problems with loading or playing back samples.  I have separate physical hard drives for all my stuff which helps with speed/latency but it's definitely NOT a requirement. all depends on your computer setup. me I don't really have any issues anymore with my current computer setup - 3.5ghz, 32gig ram, 500g ssd main drive and a 2 tb drive for samples and a 2 tb drive for projects, all running 64bit plugins and daw programs.
 
I think I remember that Komplete Ultimate 9 full install was about 300+ gig.  Kompete 10 ultimate will be bigger cause there is now more stuff included.
 
The WONDERFUL thing about Komplete Ultimate is that it comes on a USB hard drive for installation.  no DVD swapping.  I put the hard drive into usb and run installer and it goes chugging away and installs everything in about 4 hours. I spent another 2 hours getting patches downloaded from service center and installed.
