idioms that mean largely the same thing

[DaSwede]

I'm looking for sites that offer synonyms/related phrases not for words but for entire idioms. Don't have much computer time on my hands so if anyone would like to help out, that would be great.

The more sites, the merrier.

Thanks!

Thanks, TheWinner, that was fast! Am being logged off now and can't check your sites out more closely until tomorrow evening.

Just to be clear, I'm looking specifically for sites that will give me the equivalents of a particular idiom.

For instance, if I start out with "curiosity killed the cat", I want to find other idioms that mean more or less the same thing but say it with completely different words. I've had a very quick glance at your sites and I'm not sure they do that (?), but will check them out better tomorrow! Either way, they look great at what they do do, so I'll certainly return to them for one purpose or another.
