Just make sure the store has a good return policy - restocking fees sometimes run as high as 20%. That's a lot of jack......

Polyphony is really my main beef with the PA1X. You start using a lot of arranger parts then play a bunch of stereo samples and your voice-count can disappear quickly. My take would be a Tyros2 or G70 and a rack Triton if sampling is where you're at, or pick up a used Akai Z4 or Z8....

But best of luck with your sight unseen purchase......
