The answers given to you in the tweaker section are the same as I was coming in here to post.
Used one on my XG135...it requires a second PC in the HT room, very easy to learn, and when finish the results are excellent.
At that time TAW was renting them for about $185 for I believe 7 days from the day it actually arrived at my door.
I just wish there were enough of us around here that needed one, I'd like to go together with about 5 people and buy one...however I can't complain about the job my eyeballs are doing at this time.
