Mac video editing software recommendations?

I'm looking for some tips on reasonably priced video editing software for a Macbook. I'm using Sony Vegas HD Movie Studio on the PC and, by and large, it has all the features I need. It cost me about £60. Is there anything of comparable flexibility at the same sort of price on the Mac? We had a look at FInal Cut, but it appears to be about 300.

Maybe take a look at Adobe Premiere elements? I think it's less than FCP, though I don't recall how much less.

OK, thanks.
