I agree i use the advanced search page very often it's quite good and it give's you good options, the only thing i don't like with it, is that it seems to take forever to present the SERP when you do seaches with advacned quires.
I'm wild about the FAST features and customizations. The News delivery is a big leg up. I would sorely love FAST to come up with a FAST TOOLBAR, though I have to believe that is next for them. Any word?
