I've just bought a 2nd hand PC which has had the CPU heatsink removed, so it could probably do with some fresh thermal paste. I'm trying to keep my budget down though, so I'm wondering if I can do any better than $17 at Dick Smith?

I see dealextreme.com has some for about NZ$2 delivered, but some of the product reviews look like they might be doctored and the genuine looking ones question the quality. Has anyone had success buying it from there? Is there anywhere else that sells it for $10 or less?

Thanks
