OBD2/Diagnostic scanner...Matco or Snap On???

see that's just it, I'm not gonna have a full blown Dealer style shop. I'm just opening up the last 2 bays of the building to do some auto work. Got lots of requests from accounts (and one-timers alike) to do some auto work. I don't think I'm gonna need the double throwdown max zoom dweeb version out the gate. If it grows then I guess I could upgrade(?).
what year cars you work on really makes what system you use and limits it.

i.e. The Snap-On MT2500 is readily available fairly cheaply around the market but is limited to '86-'03 cars with the correct equipment and chips. I saw one on ebay a couple of minutes ago on fleecebay for $500
