I have used Tachyon a couple times and I have friends that use them too (they do great work for less than autolab). I have a friend that uses Grossman and he says they mainly work on Volkswagons, but I think I remember him saying they will work on Hondas. I have never used Autolab, but they are a site sponsor for 502streetscene.net, and everyone seems to use them in the Honda forums there. I tried to search Autolab on the web the other day when I posted and it looked like they were in the middle of a name change/move maybe. IDK... I would call around. Those are the only places that I really know of.
