Backup for me means a few CD's with my SMF's and backing routines recorded to audio... Then I use any keyboard I already have to play live parts on.

That's a damn site cheaper than a $3800 backup T3!

In the three years since I got my G70, I've used them once. In the ten years I had my G1000, I never used them at all. I figure that saved me many thousands, right there!
