Well, $20 seems in the realm of realistic, they musta changed it. For the curious among us, what was the price that it started with that was so phenomenal??
And for the guy missing a couple keys, I've got an old mangled keyboard someplace, with a number of missing keys. If the ones you need are among the still present ones you can have them, which are they? Though it will take a while tio dig it out from its tomb, and may still be at my parent's house and not here at mine, but I'll find it eventually if you're interested.
