Joey and Edd,
As you might imagine, there have been a lot of these done in the last 5 or 6 years. I have been in contact with about 80-90% of the people who have had them done and I can count the problems that have been encountered on one hand and still have a couple fingers left over. Of those, about half of any issues have been "user error", so have no fear about reliability. He does all the work personally, so the odds are quite slim that you'll have a problem.
I have a close working relationship with Joe (for over 15 years) and will continue to be in contact with him after the official retirement date. That is to say, I will help out anyone that has had theirs done through me or by my (known to Joe) referral. Joe is one of the absolute best I have ever done business with, and for as long as is reasonable (for him), I will be able to take care of you. Just let me know if any assistance is needed.
