Best vehicle diagnostic software/hardware?

[SchrodingersCat]

Hi,
A friend of mine is looking into buying some professional diagnostic kits to help out the dad in the garage. He had a few sales reps around and tried out a few in the market: A "Launch X-431", a "Delphi" PDA type thing which was shit, and a "Wurth diagnostic system" (which consisted of PC based software "Wurth Online World: WOW" and a bluetooth OBD transceiver "snooper box" which seemed a bit like old technology tbh)
The best he found out the lot was the wurth wow and the Launch X-431. He found that both could do pretty much all the tasks that he needed to do (program new key codes, airbags etc). However, the Launch X-431 costs over 3k euros and subscriptions of 690 a year. Similarly the Wurth kit costs 1.5k euros and 700 a year subscriptions.

Now, for me to help him out, I was wondering, which device would you recommend? Is there a cheaper alternative? i.e. are there chinese clones for the two devices hardware and/or cr*cked software that could do the same job for cheaper?

I have searched the forums and found c*acked updates for the Launch x431, but could find very little on the Wurth. I was hoping that maybe I could use a generic OBD bluetooth transceiver and some cr*cked WOW PC software? I would be pretty good at flashing firmware and working with HEX images, that sort of thing, so that wouldnt be an issue.

Any advice is welcome!

Thanks!
