Great thread. Lots of options. Noticed A30M and TopDon are pretty close in features, while the TopDon is half the price.
Ordered both and tested the Xtool last night... works really well and the amount of updates it downloaded on first boot was impressive.
Going to test them on the ATS's and return one. Sure like the lifetime updates on the DIY products at Xtool. Smart to get us DIY'ers into their products with that value add.
