For very small money, check out my
Casio FZ10M rack mounted sampler in the "Wanted to Buy and Sell" Forum.
The unit is mint condition, and I
am the original owner. It has a very large
display to edit samples (so a computer is not
necessary). For under $10.00, you could build a cable to connect it to a PC's
parallel port which would allow loading (and
saving) of samples to the PC.
It has 2MB sample RAM which can be divided
ANY WAY you like (up to 64 samples); and you could have one sample such as a groove use the entire sample memory if you wish.
The large display and full features are
not found in the current crop of low cost
samplers on the market.
