Brad,
Do you have a ph# for Plexi-Klass? I would like to call and see if they would ship me 2 sections (4" and 6"). Also I have seen on some DIY pages that "service joint" can be used on the top of the reactor. Large one of course and only using the halph with the oring. This looked like less work than key hole designs, but could cost more I would think.
