I've had my Pro Tools' 105 for abour 14 years. At the time did my research, and decded that was the best one for me. The biggest complaint I have with the Pro Tools bender is the backing blocks. It seems no matter what I do, I get galling on the tube. This due to the fact that the backing blocks are mild steel just as the tube is. This is more of an issue with CREW tube. The JD2 backing blocks have a replaceable bearing material insert on their backing blocks. IMO this is a better design than what Pro Tools is offering. And yes I have spoken to PT about this, and Jim just tells me that I need to polish my backing block. I've done that many many times, and it only works for the first 3 or 4 bends.
A couple months ago. I ordered a custom die from PT, to the tune of $300.00 plus shipping. When I received the die, it was of very crude workmanship, and the backing block pin hole wasn't even close to the correct location. When I called Jim at PT, he appologized, and said they had been having some employee problems. I know sh!t happens, but I just was not happy with what he offered to make the situation right. So I had to spend some more $$ on a lttle machine work, plus a couple hours of my time re-working the die and backing block.
If it weren't for the fact that I have a small fortune invested in dies (13 die sets) I would sell my PT105 and buy a JD2 #3. There's my .02
