If you want to go to the field and fly and have fun buy a DA. If you enjoy going to the field and working on your motor trying to get it run correctly, buy a 3W.
I've seen just as many problems at the field with da as 3w. Da has the edge in service and 3w usually has the edge in power. If you have never run a gas engine and do not know anything about gas engines, or do not know anyone to help you with gas engines I would buy a Da.
