ETM collet chucks and sets

[specfab]

I just wanted to find out whether anyone has opinions from experience with ETM collet chucks and collets. I need something for some applications at work, and I have an ER16 ETM set I bought used for my own use, which seems "OK". I haven't measured runout of tool shanks in the collet chuck to give me any baseline data, but I haven't detected poor quality cuts from the set I have. I have seen some new ETM sets on eBay (I think) sold by a seller in Michigan, so I am fishing for any observations or opinions, or other recommendations. Thanks --

We had a bunch of them where I last worked in NMTB50. Some solid endmill holders, shell mill adapters and a few collet chucks. I have no complaints, they were excellent.
