My only real experience is to actually try the thing on your car and see 
what it does before you buy it.

I tried two HF units that looked really nice on paper, except for how they 
didn't work (like, at all) with either my two OBD II vehicles.

It's not just limited to cheapies either... My buddy's fancy snap-on 
scanner wouldn't talk to our '93 BMW a few years back either.

In contrast, the HPTuners software/hardware I've got for reprogramming my 
'99 z28 works like a champ on that vehicle.

So... Try before you buy.  After that, worry about if it'll work on future 
vehicles.

Oh, and my other advice is that you want text descriptions of codes.  Just 
the code, while it will eventually work, is annoying as heck.
