I have one that I bought second hand a few years ago. I found it to be a big step up on any PST I have looked through. The main problem I have with it at the moment is that the helical focuser has developed quite a bit of 'play' and when imaging the optical train droops quite a bit. I think this might be why I am getting images from this scope with a funny 'streaky' appearance. As far as I can tell the blocking filter still seems to be going strong, but it is hard to tell with everything inside the OTA.
