Best deal on a 904?

would it matter what shop? Our shop did customer car work like any other garage you'd have to pay to fix something. Everyday I worked on customer cars... people from the area. Not shop owned briggs n stratton that the previous classes of 10 years prior tore down.
Would it matter what age?...
The small engines Briggs & Stratton was a sophomore prerequisite to get into the two period auto shop major for Junior and Senior year... The Portland regional competition was held at our shop so it was a no-brainer to give it a shot and of course yours truly took first place regional which automatically qualified me for state finals... Which was fun cuz we went to a big resort out of town where everybody met for the state finals... I still remember my picture in the school paper with my leather jacket slug over my shoulder LOL...
