Which engine is the most dependable, longest life and least repairs. 2 cycle or 4 cycle. Is OS the leader in 4 cycle. Or, I'v seen a lot of post about Saito, are they the leaders. Cost will be a factor, it may dictate staying with 2 cycle, but I am considering a Hanger 9 Funtana 60, or a Hanger 9 Twist. I have an OS .61fx on my Alpha 60 trainer, so far it seems to be very reliable.
Almost everyone I'v talked to has given me advise the OS is the best (or I should say best in 2 cycles, have never asked about 4 cycle until now)

I am going to the Southeastern Model Show (Perry GA) this weekend, want to keep my eyes open for any good deals.

Thanks for all the information given so far.
