im looking to buy my fist zt and i have it narrowed down to the 2006 48inch scag with the 19hp kawi eng. priced at 6500.00 out the door or the 2006 cub cadet M48 with the 23hp kawi eng. for 6100.00 out the door. both about the same on warranties and both dealers offer free demos if they cant repair the same day. just wanted to know which one i should go with?
