Thanks very much for all of your replies
I found your reply especially helpful Stephen, I think I probably wouldn't like the feel of the keys judging from what you have said. The reason I wanted to go for the PA800
hellboy was that I like the idea of an all-in-one keyboard, with it's own speakers. The triton could sit up it's corner for serious sequencing, and the PA to move around and play. I reckon i'll have to go and have a good think about things now, and start saving more pennies lol.
Possibly a PA2X if I can find one for the right money in the UK...
Thanks again guys, much appreciated
