I have been in the playing industry for quite a few years...I have played for MGM;Universal;Epcot Center; Carnage Hall,; many many bars and colleges in New orleans and in Memphis TN. My setup consists of a Roland D-20 ( about 22 years old) and a Roland U-220 Module( Also 20 years old) The truth is, you have to ask yourself two questions:
1.) Is this the only thing I am going to use my Keyboard for?
2.) What kind of quality and range do I want..i.e. how many keys...most GIG keyboards have only 64 keys and it is plenty if you are playing in a quartet that really knows how to improve...if not then, you might want to look for something that has the full 88 keys. The only question here is whether or not you want to have the benefit of weighted keys of the benefit of not having such heavy gear to tote around...reply back to john_potter2@yahoo.com if you want to really look for a good keyboard that doesn't break the bank or the back.
