JDFanatic is right, Machine finder is an excellent place to find a good tractor at the right price. It's where I found the 430 I just bought and another JD salesman I like. Shipping isn't too bad on something this size.
I've been quoted as low as $317 to ship 1600 lbs from Sommerville, TN to Fayetteville, TN dealership to dock by Misty Parker at freightquote.com
There are some 455, x495 and x595 tractors at great prices too on here and I'm sure I'll be back there searching for another tractor before too long.
