I went the Cajun Bandit Route. I have only had it for a month now... but I can say that the fit is perfect for the OTS that I converted. The rotisserie fits like a glove.
On my latest cook it was cold out... in the upper 20s low 30s... It took more briquettes than it would have on a warm day.... it was nice to not have to take all of the meat and diffuser to add more briquettes. Had I done this on my UDS I would have had a much harder time adding fuel.
All told I am very happy with the Cajun Bandit. Shipping was fast too.
