I'm not familiar with that doctor, but I have had the procedure. I agree with everyone who has posted here. Yes, it is a very rough recovery at first, and leaves a big scar. And I definitely agree you should be at or close to your ideal weight before doing it for the best results.
I'm not 100% satisfied with how mine turned out, but even so am VERY glad I did it and would do it again in a heartbeat. I used to have so much trouble finding clothes that fit right because I was tiny everywhere else but had this great big pooch on my belly and it made me very self-conscious. I worked out like a crazy person and there was no way it was going to go away without surgery.
As far as being vain...how is that any more vain than having Lasik, bleaching your hair, or getting your teeth whitened or straightened? People spend money on all kinds of things that aren't "necessary" -- if this makes you feel good, then go for it! I understand this isn't everyone's priority, but I was much happier spending the money on this than on a projection TV or a boat or something.
I would suggest getting a few consults with a few different doctors and hear what they all have to say before deciding on one.
