After a lot of research, I've narrowed my new ZTR to a Hustler Fas Trac. My yard is a little less than an acre so I'm leaning toward the 18/44 instead of paying an extra $400 for the 20/52. 1. Is this a good move or in the long run would the larger machine hold it's value better? 2. The dealer told me the best price for the 18/44 is $4500 after the $700 rebate. Has anyone done better? What $ amount in accessories should I ask the dealer to "throw in" to make the deal? Thanks!!!
