which browsers do you test in?

[LittleRed]

just wondering which browsers people test their sites in.
I'm using IE 5.5, latest Mozilla and latest Opera, but considering getting a 4.x Netscape (especially to see what happens to CSS etc.)

any recommendations? (particularly on which versions of each browser it's worth testing with)

cheers

there's two main browsers you should test in.. IE and NS
