Anyone have any experience with them (they sell on ebay)? Looking at a straight shank ER16 collet chuck and collets. Inexpensive, but want to avoid junk...

No one has purchased from them?

That guy is a favourite down here, and also CTC tools who carry pretty much the same stuff. I think they are good quality for the money. Some of their stuff is 1/10th the price for a European name-brand, yet pretty close in quality. If your needs are very exacting though, look elsewhere.

(An example: I have a couple of their ER32 collets chucks and collets. The measured runout ranges from 0.0002- 0.001 or so. By contrast I have a set of Swiss Rego-Fix which are consistently within 0.0002 or less.)

I have a few of their face mill holders and am pretty pleased.
