There are several doctors in the area that are lower in cost. I also have a link to a VR board which has a lot of information on it. It is on iVillage - You can put in a search for vasectomy reversal. Here are some doctors ...
Dr. Bird - We used him and love him! $4500 all inclusive and he puts your DH under for the procedure. If you pay in cash for the SA - they are $35 at a Scott & White facility. Here is his link...
Dr. Leverett - he keeps you awake and he does it has a ministry with the wife usually seated at her hubbs head. He has a new partner that does it as well. It really depends on if you want to be awake during the reversal or not.
There is also Dr. Wilson who is in Oklahoma. He is about $1700.
On the ivillage board, all of these doctors have been used and with success. You can also find much higher rates from 10-15K for a reversal. I would also suggest that it be done as soon as possible so that you limit scarring over and other issues. Dr. Bird has a sheet on his website that lists out all his patients and their success rate.
