In times past I have had to drive hundreds of miles to try out certain keyboards because my local dealers will only carry the most popular (and boring) models. However the internet now provides enough information/demos/reviews/forums that with effort you can generally decide what features you really need and narrow your choices. Then you can order a keyboard from a dealer who will accept it on a 30 or 45 day return if you find that you don't like the instrument. All that will cost you is postage to return it, which is less than you would spend on a long trip to a dealer anyway.

Think of the advantage this gives you as a performer - you'll be the only one in your area with a Tyros or a PSR3000! I play a Yamaha 9000 Pro and noone else in my region has one.
