I have one I like very much.
Waterproof cover, high wheel base (so if there are puddles, you don't drag the cart through the water), front zipper pocket for umbrella or other things you want to keep handy.
I've had mine for 10 years and would recommend, but it's no longer made.
Here's a close approximation, with good reviews:

I would not recommend the open horizontal style cart that PP posted. A vertical cart will be much easier to maneuver, especially on transit.
