Welcome to OCer's dot com's BBS, Mad Butter! Hope you enjoy it here.
According to what I read, the Thermalright SK-6 seems to be the best HS you can get in its price range. I don't think there's a better "light" all-copper HS anywhere. OCer's.com did a review of a new ultra thin finned Cu HS on the Front Page on July 27. It's said to rival the SK-6, but personally, I think that the fins are so close together that they'll get fouled by dust quickly.
In other words, you bought wisely! As to HSF's, I have an Alpha PEP-66, a GW FOP-38, a Vantec Si5, a Millennium Glaciator and a Vantec 60350D?? I can't remember the model number--it looks almost exactly like the Global-Win FOP's.
