I know this is getting off track just my comments on others endorsing a product. Over 2 years ago Donny raved about the Pa800 as did Uncle Dave. I got interested in the PA series based on some glowing reviews by both. Didn't work out for Donny, but I went to Frankieve's store played the PA800 I knew I liked what I heard. I bought one, liked it so much then upgraded to the Pa2xPro. Here we are about 22 months later and I'm still using the Korg PA. I did miss Yamaha and added the s900. My point is I never would have tried the PA series if it weren't for Donny raving about it, worked out for me, not for him. As far as I know UD still uses the PA800. Part time musicians have to have a frame of reference what better way than have someone who earns their living making music doing the field testing. I consider that a real plus.
