if you are going to be a overclockers get the fop38 if you can stand the sound, i'd figure the alpha with the delta 38cfm on it would be better. If you want quiet get a alpha with a 23cfm sunon but thats expensive. Or get the forged steel taisol for $33 which is also expensive. For just a good decent heatsink, you cant go wrong with the taisol 733/734 ($13/$20) or the vantec socket A with the sunon 23cfm from 2cooltek, i read somewhere that if you put the vantec with a delta fan its nearly as good as the fop38 or alpha. It has a very easy to install clip, i have one, there is this huge metal thing for your thumb. Most of the coolermaster ones are hard to install and dont cool extrodinarily well, but they are cheap and recommended by AMD. you can also go for a chrome orb or a super chrome orb, but the taisol or vantec would probably be better values. The cheapest one i'd recommend is the vantec, and for all out, get a pal6035 with a 38cfm deaf maker fan.
