Take your favorite headphones and plan to spend the day. I would recommend Frank at Audioworks as he is also a player. Other places would also be good if they have someone knowledgable, not just know how to play the built in demo's. You really need to go somewhere where they know the product well so they can help you out and answer questions. It can get frustrating trying to get a fell for it in short times. At least is has ben for me. Also, download the manual and actually read the whole thing, take it with you.
