I used to own a Mirage DSK, the second version. Not a bad sampler, but not to practical. I did not like the split keyboard, and that samples had to be sampled to the upper or lower halves of the keyboard. No across the keyboard, sampling. Plus the Hexadecimal two digit read out was not the best. Recording samples was okay, and looping was alright. I did do some cool stuff with it. Like sampling "feedback". It created a piano like sound. Which is weird, since feedback tends to be a nasty sound to begin with.
I had considered picking up a used EPS16+, but never got around to it. I always thought samplers were pretty cool. I did mess around with an ASR-88, but that was really expensive. I still see them on Ebay, that and the ASR-10. People still buy them. I still miss hardware digital samplers. Once they went virtual based, or integrated into music workstations. They just were not the same. I like the fact that, they work like the old style computers. When you had to load in programs.
I even have three books on sampling. "What's a Sampler?" A basic guide to the world of digital sampling. By Freff "The Sampling Book" by Steve DeFuria & Joe Scacciaferro, and "The Essential Guide to Practical Applications, Casio FZ-1 & FZ-10M also by Joe Scacciaferro, and Steve DeFuria.
Very well written books, but I never put them to any use.
