I live in Fairmont, Minnesota, a town of 11000 50 miles from anything. I'd
like the local A&P to be able to do maintenance on the engine, and fix it if
it breaks. I also need to feed it a steady diet of 100LL, as every gallon of
automobile gas sold in Minnesota must have at least 10% ethanol (and that's
supposed to go up to 20% in 2010).

The O-200 also runs best on mogas. They have serious lead fouling
problems.

The cylinders on those small bore continentals aren't exactly known
for their durability either.

That said, I would probably prefer an 0-200 over a Rotax mainly for
the reason you cited -- the universality of its design, anyone can
work on it, etc Just don't think it'll need less work than a Rotax.
