Princess Auto, a major player up here has some good specials throughout the year. One special I thought was pretty good is this tongue box $149.

It's not the thickest material but the fit and finish is very good. It has a gas shock for the door. Nicely nickel plated hardware. Harbor Freight has steel boxes, half the capacity and $130-$170. I think the Princess box is a much better buy.
