To me it really depends on the issue...there are many sets where if you can find a SGC 40 or PSA 3 you've really got a fairly high grade card...then many others you need a PSA 8 or 9....
Most of the really tough sets that are hard to come by in good condition I see it more like-
SGC 40 (hi-mid grade to high grade for some)
SGC 20-30 (mid-grade)
SGC 10 (low-grade)
