I am looking to replace my stock AMD HSF for my Athlon 2000+ (Palomino) on an ABIT NF7 motherboard.

There are so many different options I would appreciate some help choosing

The 2 most important things to consider are COST and NOISE.
I am looking for a price around about £10 or less and it needs to be as quiet as possible (~20 dBA?).

Cooling is secondary but obviously if it is a choice between 2 HSFs that meet the above requirements, the better cooling wins!
It must cool to at least as good as a stock AMD HSF, preferably better.

Here is a brief list of cheap ones I have seen, I don't really know how to compare without buying and trying them out!
There are lots of reviews, but they generally aren't geared toward quiet budget coolers.
Better suggestions are obviously welcome!
