Whenever i need any kind of program i first check this page:
http://www.snapfiles.com/freeware/freeware.html
So far i have got pretty much everything i've ever needed. All free and some tools are even slightly crippled versions of very expensive commercial products which still offer loads of functionality.
I'm using this page for years (even back when it was called WebAttack). It's nicely organized as well so you can really find stuff quickly. Only downside is that they sometimes need a bit of a time to update the programs and screenshots are sometimes a bit outdated. But other than that it's great.
