Most of the controllers have a connection for a pendant on them (although I've never paid attention to that bit in the manuals for those that come with a MPG built in...).

I've found another make, Weihong, to add to the list of candidates. They make the original NC-Step, however from first glance their panel systems seem to be a bit more up-market/modular. I'll need to have a read through of their manuals and find some prices to add to the comparison.

There are some brilliant translations though.
Ones that stick in my mind are the Bamboo hat, or mechanical hand tool changer, and weldings. There have been a couple times in the past where I've had to make use of a thesaurus to figure out what they've been trying to say.
