I have been on the search for a used Z.. Not having much luck. Decided to look new I have a couple of options 1. Freedom Z Scag 48" for like $5200 (kaw 19hp) 2. Freedom Z Scag 48" for like $4999 (briggs 26hp) Also which is the better way to go, bigger motor or stick to the kaw? Is there any wiggle room? If you was buying one would you try to negotiate, or is the wrong time of year for that?
