RS's, ugh. The interface on those things is annoying. It you want a slightly cheaper keyboard than the XP-80, check out the XP-60 - same as the 80, but with 61 keys instead of 76. However, Equalizer does have a point about the RS series, if the XV-88 was too expensive for you.

(Everybody seems to love the Fantom but me... I've played around on 'em a fair amount, and I just don't see what's so intriguing about them. They remind me of Windows XP - a toy for adults. The boards in the XP series are much more professional.)
