hello, could anyone tell me about 2 digital pianos i am intersted in for my son.
yamaha pf-500
techniques sx-px665

if anyone has played either or heard them ? and the difference in real piano sound quality.i would like to buy him one that he can use for at least a few years without it going obsolete,or if you know of another decent digital piano.
thanks for your help much appreciation!! ;-)

I like the Yamaha P - 90 and the Korg 300. Both have nice action and the usual selection of sounds. The Yamaha has a two track recorder, The Korg has different temperment tunings. Both are about $1000

thanks for the advise. the yamaha i was talking about is a PF-90 how is that particular model?
also i havebeen hearing alot about a casio ps-20 at half the cost and that the action and sound are incredible? one more ? is it true that technics is going out of business i have an oppertunity to purchase a sx-px 665 at a decent price. thanks for your help
