I don't have too much experience with samplers, but of the ones that I was looking at (including an akai 3000 and a Roland unit) this one had the best feature set. The unit is very quiet with -10dbu unbalanced outputs. Setting up patches is quick and simple and the alpha-numeric keypad makes name fast and easy. If you're the sort to create a lot of sounds on your computer and then dump them into the sample, this thing can quickly become the focus of your setup. My only complaints are that the lfo doesn't swing back and forth enough (needs a greater amplitude) and the assignable controlers stop around 26 (picking up again at 64) for the footswitch (you'd think they could have spared a whole byte for the things) and when you assign a controler to the filter cutoff you can only open the filter - not close it. Not a big deal really but sort of annoying.
It's expandable to 128MB of ram but only in 72pin simms which are getting very hard to find these days. If you get any memory for it - it should be single sided otherwise it will only recognize half the value (8 -> 4 etc.)
