"With a tandem, you can pull the good tire on the same side up on a stack of leveling blocks, or one of those crescent shaped levelers, to get the flat off the ground. Single axle needs a jack. "
Sounds like 6 of one and half a dozen of the other. One is no faster or easier unless you don't have a jack...:S I changed tires 4 times on my tandem axle 22' TT, 3 of the 4 times it was the right rear catching a nail, bailing wire or other road debris. The front tire catches it and throws it back into the rear and it was always on the right side as that is where most of the road debris lives.
The 4th time it was a China bomb explosion and all 4 times it was easy to just jack the trailer up {I always carry a bottle jack and a jack stand - yep, Harbor Freight} vs having to put down leveling blocks and pull up on and off of them. Whatever floats your boat.
As to the OP's original question about worth the cost, it all comes down to how you are going to use/load the trailer. I do recommend a cargo trailer as having a portable garage following along like a faithful puppy is awesome. Everything stays out of the weather and beyond the prying eyes of bad guys. It also works well for hauling everything from construction materials to tree trimmings or other landscape waste. The more I use it the cheaper it gets. :B
As always... Opinions and YMMV.
