David VarghaJim -- Weren't you aware that Network 54 is the unofficial "Bash PSA" board? You ain't cool here unless you believe SGC is God and PSA and GAI are the antichrists.
To answer the original post, SGC brings the greates ROI for pre-30's cards. PSA more than holds their own on many pre-30's cards such as T201, T202, T205, T206, Fan Craze and Cracker Jacks. By the time you get to 1933 Goudey and beyond, PSA cards generally sell for more. GAI is gaining respect in the marketplace, but trails both PSA and SGC currently.
Regardless, evaluate the card by what you see. That should always be your first "line of defense".
