I bought a simjet 2300 and have enjoyed it so much that I purchased another simjet 1200. I had my 2300 in for service (over the pond) and it was back in my hands in 11 days. I think that it is only a matter of preference of which engine you buy. But for the price, you cant beat the simjet price. I am sure that you could not go wrong with either engine. Once again, I think it is preference.
