I have the following mats, Funk Achromat, Soundeck, Herbie's Way Excellent II, and some of the stock mats that came with my tables. When I had my VPI Classic 2 I didn't use a mat. Same with a couple of tables that had acrylic platters. I can't tell major differences between them.
The only one that I tried that had a significant impact on sound was a deerskin mat that I saw some people raving about. It made things sound kind of dead. I don't recommend it.
I wouldn't worry about the adhesive. The Achromat mat has adhesive, but I doubt I'll ever take it off. The Herbie's mat is kind of sticky, but no adhesive.
