I know of a few dealers around here that have this. They are pretty satisfied with it. However, I will say this again as I have said it in other posts. What these people are charging you for is the research. If you research on google, howard forums, mobile-files.com, etc., you will get the info you need. Your best bet is to help people out when they need it and hope they are as kind when you need it. It has worked for me in the past couple of months.
I got started by simply organizing all of my files so I know exactly where to go when a particular phone comes in to be flashed. People like Cricketme.com, flashtotalk, unlocktotalk, etc. will say they offer support but by the time they actually respond to you, you probably could have found it on your own.
Best of luck in your new flashing endeavors...
