I'd still be very hesitant to buy any roaster that didn't have a solid history of product support in the US. Taiwanese/PRC builders may make marvelous machines, but sooner or later something will break or just plain wear out.
Having to wait multiple weeks for a replacement part, which may need to be custom made before it can be shipped, could leave you without a roaster for an extended period. What is a killer issue for a commercial roaster may just be a nuisance to the hobby roaster, but it'd be enough to make me hesitate.
