Back when I did the BXA tool holder testing I also compared a BXA Aloris to a Bostar and a no-name import (all three wedge types) and found the performance aspect to be negligible. Fit and finish wise the Aloris was far superior with much tighter manufacturing tolerances. My current QCTP on my PM-1440GT lathe is a Bostar CXA. I did however make a new center T-nut to remove some of the slop I felt was too excessive. I have considered upgrading but when I am able to remove and reset a tool within a few tenths it doesn't make sense for me to spend the money. It is my opinion, based on extensive testing, that most issues with repeatability and rigidity come from the compound rest on the hobby import lathes or not keeping the surfaces between the tool holder and the tool post clean.
