There are 3 types of tools.

Hand held, Cable/laptop and Blue tooth.

My thoughts, if it is for the occasional use, why spend the money on hand held, paying for box, screen, buttons etc when a laptop will do the same thing.

The cable laptop seems like a good option but that is not cheap. Is it because there are more functions available in this unit compared to hand held ?

Bluetooth units are incredible easy to make and cost even less than making a cable. Maybe this is the best value for money ?

Is there a table somewhere that lists the units and what functions they do and price ?

Is it worth (although why not) buying a $5 Blue tooth one from Aliexpress as a learning tool on diagnostics ?

Initially I don't want to spend more that a couple of $100.
