I ended up getting a Toro MX5000 for $3,800. After test driving them all (not cutting) they all felt more of less the same as far as straight driving goes. I just couldn't get the fabbed deck out if my head so I felt better going safe and getting one that is. Plus, I really liked the Kawa engine and better Tran vs say the SS5000 or Gravely that I looked at. It's being delivered this week so I can't wait to get out there and really test it.
Thanks to everyone for their opinions and tips!
