can I get A suggestion on a midi keyboard controller that doesn't have cheap plastic keys. One with a nice solid weighted feel. I currently have a behringer UMX49.

I have been wanting a StudioLogic Sl-990 Pro for a long time. Plain vanilla but good action and priced just beyond what I can justify at ~$500.00 if you shop around.

I recently (6 months ago!) purchased a Novation Impulse 61 - so far the best midi controller I have ever had - used to have an Akai MPK49 but really had midi drop out issues with that - couple of M Audio things that only ever seemed to last until the guarantee was up and an Edirol, which is OK and still in use - but the Novation is the best by a long way in my experience

I bought an Akai MPK261 and I'm very happy with it. The bottom is a metal plate that holds it all together.
The keys are plastic, I'm assuming you don't want or expect Ivory keys of a piano. (I think big btw)
I like the amount of features I have with it, as I dont have a dedicated control surface.

I agree about the cheap plastic feel and for that reason I bought the Roland A 49. It also comes in  64 and 88 and weighted as well. I like the feel of Roland keyboards. It is loaded with excellent features and bonus came with Sonar LE. I used that version to upgrade to Studio, a $ 125 value so in away I got the Keyboard for free. 
The A49 is a nice size for a desktop set up. My only gripe is it has to use USB for power so you can't easily use it away from a computer. My old Roland P200 had the standard 9 volt adaptor and even took a battery. 

I got an Alesis Q88 about 2 years ago. The say the keys are 'semi-weighted'. They are not like the cheapo keyboards as each key has a bit of weight to it. But they simulate some of the weighted piano key type resistance with springs. It seems to be well built and seems to work fine overall.
 
A couple of things though. It doesn't have any velocity curve settings so you may need to set that in each of your virtual instruments. Some instruments require me to really pound the keys to get the preferred volume or hunt down the setting in all the instruments. I emailed Alesis about the issue and they pretty much told me I was crazy...
 
Also, with some sounds, the octaves seem to be out of balance. Like C1-C2 is a bit softer than C0-C1. That only happens on some instruments so that may be a sampling issue rather than an actual issue with the keyboard.
 
Even with the issues, I think it was a pretty good deal for 88 keys @ ~$200.
