Thinking of going with the ASP 120 4 stroke...for a $169.00 you can't really beat that. I know people are not a big fan of those engines, but I am running a Magnum .91 4 stroke on my biplane 4 three years and it has been great.
From what I've read the ASP and Magnum are identical and put out about the same power as an OS. At that price you are right..that would be hard to beat. Good luck with it. Come back and let me know how it worked out.
