Hum, that’s a bit like going to a restaurant & asking the manager if he’s tried the new restaurant up the road & if he can recommend it.
For the most part the T-Bar is, if not actually in bed with Pscan, certainly on good terms.
That would be my recommendation, it’s a device dedicated to Rover products & their close relatives, you would be buying a dedicated unit, UK designed & built by an enthusiast for others who share the same interest. If you’re having problems you can come on here & folk will clamour to help. You will be able to gather more information, change parameters & enable devices, a facility which would be unlikely to appear on a generic device.
At the end of the day you pays your money & you takes a chance & if it doesn’t do what you want it’ll involve you in a lot of farting about sending it back. And it won’t receive regular software updates.
