Here's page 1 of that search:
non-rares >75 will get bid up to 300 by people who I guess have nothing better to do all day than arb 4-8 coins per card, the rare ones will get bid up to 550-600 (lower return on your capital) and are more likely to be bid on by people that want shiny cards, and at any given moment you prob have to go 50+ pages deep in that search to find any non-rare players rated exactly 75, which are what you want.
