I hadn't thought of the old 76 !! I think you are getting into something that's just too big for private use and landing in your garden ..... Also can you pick up good spares machines for around £100k ? This is the key question ..... Can I get cheap spares if something goes wrong ? Also don't really know about the engines , but the 250 in the 109 is as cheap as they get !!
We still don't have a contender to beat the good old 109
