The 355 and 427 are old technology but are relatively inexpensive to buy and maintain.
I concur with the 355 [the 109 and others] as being 'old technology' but not the 427 .... it barely exists it is so 'new.' And of course it will have to be a JAR27 build standard will it not.
Did you mean the 407?
