I have a pair of MH dress boots (I believe the Sportive High Rider II model, but I may be misremembering) and a pair of the Ice Rider winter boots. Both are extremely comfortable with virtually no break-in period. I have not had any zipper issues, either, and the zippers seem reasonably hearty.
My only grump about them is that they are too short for my calf length, and as far as I can tell, MH doesn't make a tall option. But if they're the right length for your calf, they're lovely boots for the money.
EDIT: It would seem I lied a bit. The Firenze comes in a tall/slim calf. But you can't get the regular or wide calf in a tall option.
