I want to upgrade to an budget entry level bidirectional one. (Not just a code reader.) Autel seems to be good but there are so many models. I am looking for one that can do TPMS. BT is not really needed. Reading the sensors of course is mandatory. Key programming a plus, but I know a lot of new stuff needs internet access. Not going that far. Autel MK808S-TS looks like what I need. Battery testing would be a plus. Vin reading for auto setup would be nice. Mostly going to be used for domestic. (Ford, GM, Toyota) Any other ideas?

Does Autel offer refurbs??

I probably won't be doing any upgrades. At least for a while. By that time I might be into another unit.

There is a lot of different models and can't tell them apart. MK, MX, 800 series, 900 series, Pro models, Maxicom, Maxicheck, 808Z . Seems like a lot of fairly identical models. I emailed Autel with no reply in a while. It seems to be that way with all the companies I have emailed lately.
