Well I had been planning on trying to get a
SGII for about $120 on ebay (used I guess); in my searches for
scangauge or scan gauge it picked up the auction that prompted me to start this thread. One person bid on it a few days out, I guess with a max bid of $50.50, and then when I put in my bid with 5 seconds left in the auction (I believe my max was around $70 actually) I snagged it. I'd imagine they don't go up on ebay too often...but anyway, searching for scan gauge and
scangauge are the best options for you. I don't know if this link will work; you probably have to at least be signed in on ebay:
eBay Motors: scan tool the scan gauge (item 280336206310 end time Apr-30-09 07:56:18 PDT)
That's the one I won. Good luck in your search! There weren't many details in mine, but I'm hoping for the best.
