There are really two separate questions:
The first is whether or not a surgeon having his or her own surgical suite raises the cost of the surgery (as opposed to doing it in a hospital). There is no absolute answer for this but, in general, it is usually possible to do it for less in an office or ambulatory surgical suite environment, in which the surgeon has as greater degree of control, than in an hospital, where he or she doesn't. That doesn't mean that it always DOES cost less but my guess is that it normally could.
However, the larger issue, as you've raised it, is selecting a surgeon you're comfortable with. This is (obviously) an important decisions and you want to make sure that your surgeon is qualified (board-certified, experienced in the procedure you're having done, etc) and that that's the surgeon you want. There are of course financial realities - we often cannot afford what we want - but making a compromise decision just because of price in a situation like plastic surgery can have significant consequences. There are no guarantees for this (or any other) surgical procedure, but making a decision based just on cost, if avoidable, is not something I'd recommend.
I hope that this helps, and good luck,
