200 bucks has the early and late model US car cartridges and the Asia import cartridges. I think that is all of them. has many cables, but the renix one was not included, I got the renix cable coming from ebay, 10 bucks. It also needs a new battery, it is an 8.7 volt Ni Metal battery, rechargable type. it was dead. mine is the graphing analyzer, the MTG2500, the standard non graphing analyzer MT2500 uses a disposable 9 volt battery.
Snap on wants 50 bucks for the battery, but it looks like a no name brand battery is about half that cost
Also included is carry case, several instruction books.
Near as I can tell 200 bucks seems to be the usual asking price on ebay for the non graphing units, some may or may not have the cables or carry case.
Mine appears to be very lightly used, nice condition except for the dead battery.
anyway, look for MTG2500 for the graphing function rather than the MT2500 unit, just keep in mind it uses a more pricey rechargable battery. My battery showed signs of leaking, so I need a new one.
Graphing units will plot data on a graph and have the ability to save data for later review.
