No, but I'm thinking about the Yunsheng.

The Nanjing/Intop I would assume works, or it wouldn't be advertised
by a western equipment importer. I'd think the Yunsheng item works
too, though I've only seen it on Yunsheng's site.

The issue with cheap... heck, and not-cheap too... equipment is
reliability. How long will it last with frequent and possibly extended
use? I can't say. But often enough cheap equipment can last as long as
much more expensive items, especially if it's treated roughly.
