I looked into it...but building your own PVC cages only seemed like a viable option if you plan to build alot of them. The PVC sheets used are not the cheapest thing around when you buy them individually. Then you have to cut the PVC....which is a pain.....and put it together with either mechanical fastners.... or chemical or heat welding. It is not that complicated of a process....i just would not want have to mess with it...It seemed to me like one of those things that is worth letting someone more experinced do it for you......cause I know that even though I work with pvc pipe and know how to manipulate it a bit.....if i built the enclosure, it would be all lop-sided and messed up But is just my experince with it.....maybe someone that actually builds them can offer more insight into the idea
