Maxme from Matco (made by Launch, prepare for a lot of chinglish and a terrible ui) is a viable option. It cost about 849 can have individual lines (makes) activated via monthly or annual subscriptions. IT was designed for a small shop or individual owner (aka freelance mechanic) whom wanted a more capable scanner like a full blown shop scanner just without the cost. I had a Maximus from Matco, which is an fully unlocked version or the older brother of the Maxme. It will have bi-lateral capabilities and is pretty usable. From playing with the Maxme it is has slightly slower hardware, couldn't use the borescope from the Maximus, entry point and stuff was the same in both. Some PIDS were not available with it. I like the Versus pro better, but you could almost buy a 3 year old car for as much as it cost not including annual subscriptions.
I personally, wouldn't carry either shop style scanners on the road. I use Torque and my cell phone to monitor vitals and look at any codes. Really wish it could read the wheel speed sensors on my truck.
Just Saw this might be promising
