HSF - whats your pick?

SO, i've ordered alot of new parts online. I bought a Vantec CCK-6040H which i have read reviews on, its a decent cooler, but nothing hot shot-ish. SO i thought i'd do kinda a poll, what is you guys' pick for best HSF (I hope to be doing some overclocking on this rig) I would say, price range <30$ US.

The CPU is a AMD 2000+.

Also- how can I tell if my CPU is manuf. on the .18 or .13 manuf process? is there a simple easy way?

So if any of you have opinions on HSF units that don't cost more than half of my CPU price, post here.
