And ridiculously overpriced in my opinion....

I understand all about mass production and how it can lower prices, (addressing the fact that you can buy a chain saw or other tool with a similar sized engine for 1/3 the cost), but I just can't see paying that much for an engine.

I've been very happily flying numerous airplanes with engines converted from other equipment for years now. They perform extremely well, and the most I ever paid for one was $80.00; most I got used for 10 bucks or so and rebuilt for less than 20 dollars.
