MicroTEC
I do... on my Mazda MP3... they are very nice units for a lot less money then some stuff out there. Very reliable, and the new units have a lot going for them. Incredible software suite as well... I do sell Microtech as well after I was a user for a good while. I have not done anything on the Evo's yet... nor do I have plans to at this point. But I can vouch for the units as quality and doing a great job.
