Here's 6 more reasons......

1) I just want it... it's pretty
2) Fran has one ... I want one too !
3) It does this ONE thing that I reeealy need
4) It was so cheap, I couldn't resist
5) My other gear was lonely
6) I didn't want my competitors to have the last one!

My one and ONLY real reason:

To make my living, by accompanying myself. Period.

I don't really love ANY of the arrangers I've seen EVER. They are all just different degrees of substandard. Some are better than others, but they are all lacking something.
My bass guitars have no compromises,
my clarinet has none,
my flute has none,
my guitars have none

If all these instruments have fully evolved - why can't the world of electronics ever "level off" at an acceptable place that we can live with, and WORK with for a LONG time. Remember when all you needed was a Rhodes ...... or a Hammond .... or a DX7? Life was so simple then, and the choices were much easier - just reach in your pocket, and buy the tool that really worked. If you needed two or three, then you just has to get them, that's all. I carried a MOOG for YEARS as a bass. It was great too.

I can't remember EVER hearing so many diverse comments on good vs. bad in keyboards. There was always the personal taste issue, but at least the design features and reliability were there from the start.

How many Sax players ever switch horns after they get the good one? Look at your favorite bass or guitar players' amps - the ones that work a lot have the most wear on their gear. I was at a jam last night that had thirty year old gear ! It was very nice too. Acoustic piano, drums, bass, trumpet and me on clarinet. We had a ball, and NO NEW GEAR. None at all. Just friends making music to honor the memory of a fellow musician that had passed on. NO charts, no tip jars, no AUTO anything. Just good, solid, live entertainment.

I know I am among the most fickle, but it's not by choice. The manufacturers won't build what I need. I'd LOVE to have the same keyboard for the next 10 years and be happy, but that ain't gonna happen!
