I need some new MT2 collets for my Bridgeport M head.

An outfit named Discount machine Shop sells a set, but they aren't very
pricey, which makes me know they're off-shore stuff.

If you've ever bought from them, let me know what you thought of their
quality. I don't want collets with a lot of run-out, but I cannot seem to
find an authentic Bridgeport set. (for which I'd gladly pay)
