Go with the one who offers the best dealer support. Last year I bought a $4000 tractor and the first time something happened they wouldn't service it! What a nightmare!!! Down for 3 weeks till a local family dealer helped me out.
Its been said thousands of times before... a great dealer behind you is priceless!!! I'd much rather take a sub-par machine with a great dealer over a sub-par dealer with a great machine! All machines will break down...but a great dealer will keep you mowing! Good luck!
