I'd be hesitant buying from someone at the squares. Most of the sales are from Villagers who are honest about the condition of their cart, but the exceptions are enough to make me very wary. If you know of someone selling, I'd go that route first. Second, a friend of a friend. Third (and probably the best choice), Jim Followell. He stands behind the carts he sells, will repair things at his cost if he feels the problem was his (i.e., bearing going out 5 months after cart sold), he's reasonable in his prices.

As to driveways, I haven't found anyone I would really recommend. It seems they are good one time and awful the next, so it really seems to be a matter of luck getting the right guy at the right time.
