You can find your local official Subaru Robin dealer thru Robin America's site. I haven't priced one in a while, but Staton used to undercut my local dealer, selling at list price, by more than $35.00 to $40.00 for an EHO 35. They also sell several larger than stock fuel tanks, a worthwhile addition to any bike intended to be ridden for any distance. I used both the 3/4 and 1/2 gallon tanks on different bikes.
In my experience, you can trust Dave Staton to be true to his word, to treat his customers fairly, and to ship in a timely fashion. Sometimes he doesn't ship the cheapest possible method, but he will ship via a reliable shipper.
