I am looking at getting a code scanner for our '96 E320. Does anyone have any experience with these from Alpha-Bid on eBarf?

If they work it would be worth it, they are less than an hour or 2 of shop time, but I'm always a little leery of the sellers on eBarf.

Any recommendations on scanners that work well would be appreciated.

Thanks,
Doug
