3200....you have nice taste! Looked at them last winter before looking at ZTRs, they are built.
Anyway, just to make things confusing [I'm worse than a broken record, but I will admit more often than not, the twist I'm suggesting is not the right tool for the job]....if you're just mowing, have you considered the Cub Cadet M48 Tank [ZTR instead of GT]?
If the hill is your only challange instead of obstacles, that 3200 will be your friend for a long long time, but if the hill isn't imposible and you have trees and ornaments, the ZTR will save hours on your engine and yourself.
Of course, if you have garden work in mind, then the GT is still the no brainer.
Didn't see a location in your profile. Is there a slow season for mowers? As mentioned before you should be able to shed a few hundred $$$ on a "left-over"; though with the deck you may have a pretty good price already.
Also, if it wouldn't destroy your pricing or get too wide for your gates or trees, I'd consider the 54 or 60" deck to minimize the turning radius (27"? not as tight as a cheapo LT, but pretty impressive for it's size & weight). Reading this thread curiousity got me and I had to look up the specs: misprint? or do they actually use 13ga instead of 11ga [much thicker] on the 50"?
Regardless, you obviously have good taste in machines and will be very happy whatever you decide! /forums/images/graemlins/cool.gif /forums/images/graemlins/cool.gif
