@Eclsnowman In regards to the bowden tube pushing out, it is possible that the OD of the tube might be slightly larger on yours or the exact mixture in the PTFE might be different, causing some of us to have this issue. It is also possible I ground off some, while trying to thread the tube in the nut, causing it to fail under stress. I have had a couple of more clogs since then, but the tube has not pushed out.
I have had almost 0 problems printing PLA. It is my preferred filament. I do need to print some ABS, but need to modify my Hot End cooling bracket to not blow on the print, before I try the ABS again. Hopefully this weekend… I also just ordered some Taulman Bridge and am looking forward to playing with that soon. I am sure this extruder will have not problems with it, not sure about the rest of my printer… 
I would like to invest in one of these for my Herculein build. How do I get on the buy list, and what is the price?
Oh, and 1.75 style
