Here's a relatively cheap option: the Weize hitch rack currently on sale for $150 (or there's a foldable version for $170). Rated up to 120 pounds for 2 bikes. I just assembled and used it for the first time today. Definitely not as nice looking as the 1up Surrey Pete has, but it's sturdy and wasn't too hard to assemble. Works with fat tires and long wheelbases.
One downside: not super quick to remove from the hitch. You have to remove the towing pin and also loosen a couple bolts. It does have a nice feature of tilting down to allow use of the trunk while bikes are on it, though.
