It's just that your idea of a "decent" price is probably downright indecent.
Sort of. But not really. I'd pay 3 times what I paid or more for the cr*ppy M-Audio keystation if it was for pretty much exactly the same thing but built well with a credible piano action.
It's just that no one seems to have figured out that maybe some people want just an excellent quality keyboard without it trying to be a control surface (at which they mostly all s*ck b*lls anyway) in the mid to high price range. In that price range, it's like they feel obliged to cover the things in as many knobs as you can possibly squeeze in, just to render it impossible to put your wireless keyboard and mouse on top which would be actually quite useful thank you very much. Perhaps they think everyone wants to impress girls at gigs: oh wow, you know how to pilot that thing? It looks like NASA mission control.
I doubt I'm the only studio-based composer that could use a high quality, practically designed keyboard that really, honestly, just needs the thing to have the most basic midi via USB, and for most of the cost that goes into making it to be purely spent on building a keyboard of quality that is a pleasure to play.
It seems to me there are only 3 unsatisfactory ranges of choice on the market nowadays: you can either choose basic and uncluttered, but cheap and rubbish. Or, more decent quality keyboard but cluttered with useless overcomplicated knobs that seem like a great idea at the time but end up never getting used.. Or, really expensive with great piano action, but enormous and for the most part, ugly as sin.
My prediction is that once the ipad and perhaps other control surface technologies start coming on steam, someone (hopefully not M-Audio) will figure out that there's a market for a great keyboard that feels like a real instrument again, with all the sleek studio-friendly design angles anyone could wish for. Prediction is perhaps too optimistic.. Let's call it a pipe dream for now.
Apologies to the OP for my ongoing rant..
