Where's the pics everyone promised???
I'm ordered mine this week--I've been looking for awhile and this is what I found for anyone else looking for one: I looked at several brands, and ended up choosing InterstateWest--they seemed to be about mid-range as far as price and quality, plus they're the local dealer here when it comes time for warranty issues. I was also impressed with Pace, Haulmark, and Wells Cargo too, but ended up keeping my money local, plus Interstate gave me a fair deal.
I ordered a 7'x14' tandem axle with brakes, asphalt undercoating, lifetime warranty on the roof, z-channel steel construction for just under $3500. If I remember right, the 6'x12' was about $2600, but I've looked at so many that I can't recall the exact price. They had a million options from there (door style, colors, windows etc), but that's the basic setup. They had fancier options too, but since my trailer will mostly sit on jobistes for storage/advertising, I didn't see them as necessary.
Anyway, hope that gives everyone in the market a rough idea of cost/options, I'll post pics as soon as it's delivered.
