I think VMWare fusion is worth the 70 bucks - I find the performance much improved from the others options out there and it just works. I like to set up a couple of spaces and stick whatever VM I am running in full screen mode in one of them so I can quickly switch between the mac and VM. You can also use fusions unity mode and run IE or whatever other application you need along side your mac's apps as if they where native to OSX.
