I don't mean to "put down" the brand by this, but I'm very hesitant to spend 30K or so and be uncertain of parts availability or reliability down the road. The 6530 has some very enticing features though. Price plays a part in everything I guess, but I'll most likely spend a little more and feel more comfortable.
Dealer service isn't the question. They are established and sell several brands. I think they picked up the Branson's for people shopping strictly on price.
My wife had a sedan built in Korea once and I still get indigestion when I think about that experience!
I don't feel you are putting down the brand. I find myself wondering if I should have went with a name brand, then I fire mine up and I realize I have nothing to worry about. I also bought mine from a good dealer. Then again, I didn't shell out 30K either. The 6530 is a nice tractor indeed but, I would also be apprehensive. I would recommend getting what makes you happy not make you worry. Best of luck.
