Frame geometry/sizing question

So I was wondering, am I likely to find a 52 square frame other than a track frame? I'm trying to figure out how to do eBay searches, though that's not going well for me. How do you guys who get all these intricate searches on eBay do it??

Searching for specific sizes on EBay is'nt very effective as people dont always the same standard to qoute size.

If you fit a 52 top tube, then a non compact geometry road frame will likely have a 49/50 cm seat tube. If you go with compact geometry, it could be as low as 44 cm. But the seat tube length is pretty irrelevent TBH. You should'nt really experiance more toe overlap with a smaller frame, as this is compensated for by increasing the seat tube angle and slackening the head tube angle (can sometimes be a problem though).
