Having owned a 269B I can tell you it was cheap to buy but expensive to maintain. This was due in part to the previous owner who let a lot of things go. But I can say I loved the little beast which could barely manage 80 mph and carry 2 pax.
In comparison, the R22 seems a lot simpler to maintain as the Hughes has all sorts of odd component times. If you want more info, PM me and I can fill you in on the specifics (and the horror stories about the cost of some repairs!)
