I have used two no-name import BXA clones, the Aloris BXA and have the Dorian BXA on my PM1340. This is one area where the original brand-name units are absolutely head and shoulders better than the clones from China. The Multifix and PWE are indeed very nice. I've worked with both on lathes owned by other people. The principal advantage of that design is if you have a solid tool post that replaces the compound - the Multifix on a solid tool post gives a lot of the lead angle adjustment flexibility. But if you don't have a solid tool post, I don't see much advantage to the PWE. I also have over 30 indexable tools in QC tool holders and can't imagine tooling up to that extent with the expensive PWE tool holders. Just my 2 cents. I'm sure you will be delighted with the PWE - I mean, after all,
Stefan Gotteswinter is now using one on his solid tool post.
