I tried out several scags a couple of years ago, when I finally purchased a new zero turn (had a simplicity cobalt), I went with the zd326P Kubota.   I have no regrets about buying this mower.   It has all the power you need, plus it does my small hills pretty good.   I liked the f series, but couldn't justify the extra cost through my better half.   I also have a good Kubota dealer in Okawville Illinois that is excellent to work with.
