I find it's a bit of a can of worms in regard to pricing. If you have them too cheap, people won't go near them, and the same if they're too expensive. I usually let people know the price is negotiable and go from there. It all works on the demand.
In Bendigo, I find that $120-$160 for good 2 strokes, $140-$180 for good 4 strokes, personally I would remove the engine off the GMC and put it on something else. I find the boxed in discharge area blocks up very easily and stops the catcher filling properly, and customers don't like it. I've got a Rover here with the same base pressing as well.
Cheers.
