Yeah, I got tired of that nonsense a long time ago and just stopped even reading some of the forums up there. My honest opinion is that MANY people up there slamming LS are just trying to justify how much more money they had to spend on their "name brand" tractor to get the equivalent value in a LS with the same capability. There maybe some legitimate arguments for going with a particular brand over LS (large dealer network, faster parts delivery, etc...), but clearly much of the bias is totally unfounded. The one that annoys me the most is the supposed resale value of the name brand machines. I generally avoid used powered equipment regardless of brand unless I know the person selling it. Besides, if you do it right, you try really hard to get what you need the first time.
I just feel sorry for all the newbies asking what they should get in the "Buying/Pricing/Comparisons" forum. The answer is pretty much always the same: If you can't afford a new JD/Kubota/NH (or whatever) then you should get a USED version of one those -- even if you really know little or nothing about it and it comes with no warranty whatsoever.
