That does seem to be true. I've been doing a lot of searching for a "cheap" winch alternative and I actually haven't found anything bad about the Tmax winches. Most of the searching I've done is on Pirate, local board, and here.
I do believe some of it comes down to anticipated use, kinda like building the entire truck. With the wheelin I've done this past year I can only think of 1 time a winch would have been needed. In that case I think you can use something like a Tmax.
I was a spectator on an extremely hard trail that 38377k5 & some other CK5ers ran, and every single truck and buggy had to pull cable at least once. If you're doing quite a bit of that type of wheelin, I'd strongly urge you to spend the money on a good Warn or Ramsey winch.
The other thing I figure is if the Tmax or similar winches are cheap enough, try to get the highest rated winch you can. That way you aren't running the winch so close to its limit.
