Reply to Advice on keyboard controllers

I'm looking for a new keyboard for the production side of things. I'm on the simple MPK mini right now and I have just overgrown the limitations it has.

What I am looking at right now is something along the lines of the MPK 49 or 25; a controller with pads (hopefully good ones), and some good keys (I'd like to get 49, but 25 could do; maybe with aftertouch and some weight to them).

Other than the MPK series, I am not very knowledgeable in this area and any suggestions on what to get would be great. Price range is anything below $500.
