I know these have been discussed a lot, and I've read most of the threads, and I've seen just enough negative on them to make me cautious.

I've read both of Clarence Lee's reviews- the 90SP and the 120SP- and he really liked them and recommended them. He didn't have any of the problems reported by users, and the engines he tested were older versions.

I'm thinking about getting a 90SP for my Hangar 9 Camel.

I'd love to know what the "final" group opinion is.
