My feelings about the equipment I buy changes with time. I generally do not wrench for fun. Not knocking it, but it is not a form of entertainment for me. My B-I-L seems to love it. He has a stable of ancient tractors and even though he has a million things to do he almost seems to enjoy tearing one of them apart to fix something.
Since I don't do it for fun and don't have time to do it anyway, I bought a new tractor in order to avoid 'shop' time. I bought what I thought (and still think) was the best tractor that my budget would allow and would meet my needs. Having spent that money on a new machine, I do not intend to sweat the small stuff. That is the manufacturer and dealer's problem. Its new, its expensive and it dang well better not have any small stuff. (For the record I've had one o-ring go bad on the rear remote, I didn't sweat anything, it was promptly fixed by the dealer under warranty.)
As time goes by, warrantys expire, the machine gets paid off, that huge expense becomes a distant memory, rust,dents and dings and the normal wear and tear and a fair share of abuse begin to take their toll. At which time I get less picky. As long as all the major functions of the machine (whatever it is) are working, I'm generally happy.
But I don't think there is anything wrong with being picky and expecting quality and durability when that is what you are paying for.
As far as brand loyalty and all that, I think its natural and its fine. Like anything else it can go to far. I'll defend any purchase up to a point. But when that point arrives, that brand will lose my loyalty big time.
So far (2 years) I'm still thrilled with my purchase and other than the leaky o-ring, the only problems have been inflicted by me.
