Just as a follow-up on my initial review, I was able to use the UDM on two cars this weekend, and this machine simply kicks butt. I was amazed at the correcting ability compared to the PC. The UDM refuses to bog down like the PC. Both details were much quicker than I could have ever gotten with the PC, with better results to boot. I was thinking about getting a rotary, but now I honestly don't see a need due the results I am getting. Unbelievable machine. In my initial review I said that if you have a PC and only use it occasionally that it might not be a big leap. Well I whole-heartedly take that back! You have got to get this machine!
