I just picked one up(about a week ago)from Steve at SpeedTechRC.
Here's a pic rotation of it
There are no True graduated scale, just some lines on the dial and one on the base. The Cutter is pretty good, it cuts well but I've only used it for about 6 set of 1/12 tires and about 5 sets of 1/8 tires.
I got this one because the Airlines lost my Ofna truer, this one MOD-ed with a better motor, but the standard motor is fine. I just like to hog cut the first cut on new tires...
The Integy I got for 1/12 tires, but bought an 1/8 arbor just to have, and to try it out.
The Ofna is better if you going to cut lots of 1/8 tires, the auto movement of the cutter is really nice.
The Integy you have to move the cutter from a dial on the far side. For Sedan tires this isn't really a pain, and it works well on the Sedan tires, 1/12 is also easy to do, both cut really clean on the final, depending on what your final cut depth is. On 1/8 tires it works, but the motor can't cut the hog first cut I like to make, but none of the other truers will do this anyway, except the Cobra AC cutter, the really old one. I've cut 5 sets of 1/8 tires, so far but using the dial movement is getting to be a pain. If you true your tires as you go this won't be a problem, I just get lots of tires from friends, and stuff... I'm probably going to remove the dial crank and use an old electric screw driver for this, when I get time. But when I get all the tires cut I'l probably put the crank back on.
The newer Cobra AC motor doesn't seem to be as powerful as the older one I had, but I didn't really know the condition of the Newer truer, I was using one that someone had at the track, and running off a generator, when I did the hog cut it really ramped up the generator!!! But because its off a generator I really don't know if the motor was getting Full power... So this could be the problem...
Cobra DC(battery powered) is ok, but for me you need the micro adjuster thing(can't remember what its called), I really didn't like the place by hand using a ruler thing with the stock setup, I got one awhile back with the micro adjuster, but using a 540 or car motor was... well ok... It works, and it does a pretty good job on the finish cut(You need the snake cutter thing), for the size it can't be beat. Plus you can use any motor you have with you to run it.
For the money you can't beat the Integy... If you find your self doing alot of tires get an old electric screw driver and mount it were the crank goes.
Hope this Helps.
