"The Kurzweil K2500x and K2500sx. This is a fully blown one but just under the maxed out model. It costs so much less but you get just as much. You don't get the brushed chrome exterior. I bought my first one at Sam Ash and I'm very happy with it. I was warned that the manual would drive me crazy. It turned out that I still haven't gotten through the manual but at a certain point in Kurzweil-eezz – when you're going through the thing and at a certain point in using it – a light bulb comes over your head and you say "Ahh, this is the method you're using.” This is how they distorted Ray's vision" (Jim's talking about Raymond Kurzweil, the designer of the original K250). I got my K2500sx from Kurzweil. It's fully blown with an internal hard drive and lots of memory. It's really a wonderful machine."
