I've found a pair of Sonic auctions on E-Bay that could prove interesting, especially this first one....

The first one is all 26 eps of SatAM Sonic on tape. However, be prepared to shell out some major cash....

The second one should be interesting to all you aspiring artists out there. It's a How to Draw Sonic and Friends book. Unfortunely, all outside the USA are out of luck, as this person only ships within the states.

Just a couple of things I felt worthy of pointing out to y'all.
