I went to UTI in phx, about 8 yrs ago and I was not impressed, but I did have a pretty extensive mechanical background before I went in,(let me clarify that a little, I grew up on a small family farm and we fixed all of our own equipment and vehicles etc...) so there was only a few things in each class that I picked up on. But if you are realatively new to the whole mechanical deal you may be a prime candadate for uti. My only reason for attending uti was to get to their BMW graduate program which I will say made the whole deal worth it, I learned an unbelievable amount of info in 6.5months, and got me a pretty cool career.
But having said that, when I was in the BMW program there was a student from the boston area that had attended New England Tech and he had also had a pretty good mech. background before school and he spoke highly of new england tech. so I see you are in Mass. so you may want to check them out as well.
I did a google search and came up with the following website

hope this helps
