For low end or general applications i would recommend the Thermalright Sk6+ heatsink and the Sunon/Delta 60 mm maglev fans. they are fairly inexpensive, and sk6+ can be had for $25cdn and the fan for $20. this will give you the ability to overclock some, have a reasonably low noise cooler and one that is space efficiant. the magneticly levitated fan has no bearing meaning it will not wear out. it will also produce less noise as a result of almost zero friction operation. if these fans were available in 80 mm i would get one.
You could also look into the sk7 with pretty much any 80 mm case fan. I am currently running a lapped sk7 with a cold cathode case fan to cool my stock clocked xp 1600+ it handles it with no trouble. It is kinda large though.
