Hey Squeak,
If you can't afford a X1 I have a slightly used MS100. It's styles are very similar to the X1 and sounds to. It is still being made currently and has a retail price of $3100.00.
It has 76 keys, no speakers, a hard drive like the X1HD and still plays midi files like the X1 and has only 99 factory styles. It really sounds and works very similar to the X1. At the current retail price, I suggest the X1 or SD-1 (76 key version with no speakers) but at a killer used price you might like this alot. Email me if you are interested and I will give you more details.
