Reply to 88 Key Midi Keyboard Suggestions

So I know this thread might be better suited in a different community , but I thought it might get the most exposure here. I'm in the market for an 88-key MIDI keyboard; there aren't many of them. The main reason I want to buy one is, well, because I want to take piano lessons and I don't have the money or real estate to buy a real piano or a digital one (and it makes more sense to go the MIDI route, anyway).

The ones I've been looking at are these Alesis and M-Audio models. Unfortunately, I don't really have the opportunity to try either of them out before I shell out the money for them (they are both US $200). I'm learning towards the Alesis model. $200 certainly is not my maximum price but it's definitely in the ballpark (ie: $500+ models are out of the question).

Both models seem relatively new and don't have any reviews available. Do any of you have a better suggestion or have experience with either of these?
