NickThe old SCD (Sports Collectors Digest Authentic, with the red logo) grading is solid. I purchased 3 cards slabbed by them, and have looked at dozens more. Their application of grading standards and knowledge were at least better than BVG, and probably on par with GAI from what I've seen.
Stay away from the new SCD (Sports Cards Direct, with the blue logo). They bought the equipment from Sports Collectors Digest, but otherwise have no affiliation with them, and give every indication of being just another offbrand grading company.
