Re: [TCML] Primary Support Materials

So we know to definitely NOT use PVC in this application since it's apparently prone to carbon tracing, and the best options I've heard are the typical HDPE, and polycarbonate.
Now, I've heard that the HDPE is difficult to glue, and a weak bond at that. Is that right? Polycarbonate should provide a strong bond I would think...
As far as machinability goes, how does polycarbonate behave under a drill press and jig-saw/dremel? I know HDPE is messy, but I find it moderately easy to work with.
Lastly, there's price. As far as I'm concerned, that's just a matter of whether it's worth it or not.
What do you say guys (and gal(s))?
HDPE or polycarbonate?
Thanks a lot,
