I have the moates quarterhorse, uses binary editor and EEC analyzer also. Also have a innovate lc-1 wideband for datalogging air fuel ratio. 250 for qh, I think 80 for be, 60 for EEC analyzer, and and 180 for wideband. It's definitely cheaper than a tweecer. Depends on preferences which one to get I guess. I don't know much about tweecer, but the qh is great and has good support.
