I've been looking for awhile trying to find a "tub" or bag that has wheels on it.

It has to have a nice big sturdy handle for pulling, and big sturdy wheels. Not the kind of wheels that would be relagated to the airport. Can be hard or soft, preferable hard sided. If its "soft", durable material. Would be nice to have a second handle for lifting. Preferably lockable.

Any suggestions? I looked at all the stores around here, and only found a cooler that looked similar, but was a little thick on the sides, and reduced the available room on the inside.

Edited to add: The ones I see alot have little roller skate wheels, wanted wheels bigger than that.
