One thing you can also look at if you can handle a larger pallet jack are "dual direction" versions. If you lift them all the way up it tilts over onto a second set of perpendicular wheels, allowing you to move sideways instead of sawing back and forth to get the right position.
Overall, I think the minis are the best bet. I wish I'd bought this one from Grizzly instead. In fact, it's on sale right now, I'll probably get one and sell my old one.
UPDATE: Ok, mine's on the way. Off to craigslist I go ...
