They have been around for a few years, and I've seen them posted on other sites and the people that have them seem to be happy with them. I'm a little skeptical of the small waterpan, but its nothing that couldn't be modified if it was an issue.
But I'm with Romulus, I've got all the Cajun Bandit schwag for the 18" & 22" WSM/Kettles that its about the only aftermarket product for the 26.75" OTG, and I'd be hard pressed to mount the center section loaded up with heavy meats with the spindly legs by Weber.
I'm planning on modding my 26'r with a Ranch frame and then, I'd feel better about a Smoke EZ, but I have an 85 gallon UDS that gets little use these days that would make the perfect hillbilly Smoke EZ clone- and the 26.75" lid and Cajun Bandit rotisserie ring fit it perfectly. I think I paid like $80 for the 85 gallon drum.
