I just had to express my joy!
I picked up an E5000 Ultra from ebay for ?127 in a flight case with 128mb ram, not a bad deal I thought, but then when I got hold of the thing I opened it up to check out how to get a hard drive in there, and there was a 40gb drive already in there! Bonus!
Anyway, it's a very nice sampler, having had and ESI-32, ESI 4000 and 2000, it has a much nicer sound to it, a lot cleaner.
Now I just need to get the thing SCSI'd up to my PC and I'll be happy.
