I'll agree, heating through PVC is kind of a pain but I never use UTHs, even on my glass tanks. Everything I have is heated with either RHPs for PVC or CHEs for glass tanks. I use 2"+ aspen as bedding so UTHs to me are useless. And yeah I guess in Canada ordering to US the shipping would kill you. Here its usually included in the price or in the case of AP cages, its anywhere from $45-$75 depending on the size and where in the US. And yeah for a small snake, a glass tank is easy and usually cheap but for a 6' snake you need a minimum 4x2 cage and an 8' snake you need 6x2 minimum. A lot of people use smaller but to me, the length+depth of the cage should equal the total length of the snake at minimum.
