Hi OM:
Congratulations on getting the procedure done. now all you have to do is wait to see the results . You seem to have done your homework well on the different options and research going on, but as thanatopsis mentioned, 10K is a solid amount and should be more than enough to give you decent coverage.
On the 'current' research going on, don't hold your breath; I've been reading the same research for nearly 5 -6 years now and there has been minimal progress. Also, don't waste your money on a laser comb. I remember reading a fairly comprehensive thread on the benefits (or quackery) of laser combs and laser therapy on this forum - I think it will help you in making an informed decision.
Who was your HT doc? Also, any reason you decided to go with only 2600 grafts?
