We had the opportunity to compare the launch x431 Pros mini with the more expensive launch model. The software is the same, the only differences are in the hardware (bigger screen, more memory ...). So for me, the Pros mini is the best buy (like this one : https://www.ebay.co.uk/itm/Full-Sys...426377?hash=item3b2c9b0149:g:NyAAAOSw8bBefxTA).
Don't buy the CRPxxx version, it will not work (at least for the PIS setting).
