GtE is spot on re the 582.
I've owned 18 aircraft in 27 years. Two were Rotax 582, and the others were Lycomings, Conti's, Jab's and one (dismal) HKS.
The only engine that's been totally reliable* in my 3000 hours is the 582!!
* Starting and cheap to maintain.
Lyc's and Conti's have all cost me thousands to keep flying over the years - largely because they're so friggin' old, and many have been abused, requiring lapped valves, new rings, honing etc etc. When(if) a 582 gets troublesome, £3k pretty much buys a new engine for another 5 years!! And, it takes about 2 hours to fit it!!
