Thanks everyone for your help!
I brought the table home today and think I got a good deal! And the original glass platter was there after all. It was just hidden under another platter and I didnt see it at first.
I ended up paying $750 for the Rega 25 (with Glass Platter), Exact cartridge, Funk Acromat, Sheer Audio Platter, a Ringmat, JA Mitchell Solid Anodized Aluminum Record Clamp, and a Tranquility Base 1 (which I can't find any info on, but it's nice). I got all the paperwork and original receipts for everything (no boxes unforuntately but I can't gripe at $750).
I think I did pretty darned good!!!! I'm stoked to get it hooked up -- hopefully my Sunday project.
The cartrige install protracter is missing and so is the original felt mat.
Since I got the Ringmat, do I need the felt mat or is the Ringmat a suitable replacement? The Ringmat isn't as large as an LP so I don't know if I really like it. Is the Ringmat a good enough barrier between the platter and records??? I'm thinking I'll order a new felt mat.
