Hi Guys,
well, after a lot of to-ing and fro-ing I ended up ordering a dgx305 ( sight unseen ). It's mainly that it loads & plays a psr style, which is what I'm primarily after.
I had a listen to some of the casio demo's on site, and they sounded amazingly good, but the dgx fits in better with what I'm trying to do.
Really can't beleive the quality & features of the lower priced keyboards nowadays. Could have bought 6 dgx's for my 1 clp170 piano ( don't know where I would have put them all though (haahaa)

best wishes
Rikki
