Man, are you crazy? I just bought 2 BX1500s for the price of that - plus did I mention that a SCUT is a much better value than a large L&G tractor? Oh, sorry, thought I was someone else for a moment...
Seriously, a very nice unit - pretty much the newer version of the 455 that I have. For additional stability on hills you might want to consider wheel weights. I have a moderate sidehill mow that I can't avoid, so I run weights on both the front and rear wheels year 'round. It's probably not critical, but it does add a comfort factor. The suitcase weights on the front probably are not doing much for you - really only need them if you have a very heavy attachment on the rear.
