I think sga (stadium giveaway) rings are interesting and lately the quality has greatly increased over older sga rings. You can find them on ebay. I havent purchased any non-sga replica rings. I personally feel like non-sga replicas are worthless. When I first started collecting rings I purchased a minor league players ring, and made some smaller purchases until I figured out what I was interested in. Right now people are undervaluing salesmans samples due to the market being flooded with fakes. I just picked up salesmans samples of two of my favorite world series rings. I feel like I won the lottery with the prices I paid.
