I don't know much about prices, nor do I have personal experience (yet).
But I can say that I'm also looking to have keyhole surgery and Fischer is pretty much who I've decided on. From what I've seen, she's the best. McLean has some good results too but I haven't seen a ton of pictures. Menard hasn't really convinced me yet, however, and he's in Canada. (But so is McLean.) The only other surgeon I've considered was Brownstein. He's in San Francisco. Usually does great looking surgeries but I'm not sure the keyhole method is really his forte. Fischer, on the other hand, really seems to know what she's doing.
I don't know where you live, but if you're in the US I would definitely go with Fischer. She's in...Maryland, I think. Well, she's definitely somewhere that'll be cheaper than San Francisco or Canada (unless you live in Canada...and I'd advise you to check into McLean if you do.) Hell, even if you do live in Canada I would say go with Fischer if you can afford it.
Money = results. It's know it's hard to not think 'well...it would be cheaper to go here.' But it's your body man, I think it's worth a few thousand more if you get better results.
When are you looking to have surgery? I'm shooting for next summer ('08).
