I've been reading all of the stickied threads on building DIY racks with wild abandon, but I have to admit, building a rack seems quite different than any construction or building I've done (pretty much all larger art pieces).

So I'm a bit confused and curious as to which DIY rack design is the best to start with. Really, which would be the simplest to build while still being sturdy and able to last. And the part that worries me the most is attacking the heating elements properly.

Am I, as a beginner, better off with purchasing a rack when the time comes rather than attempting to build one this summer, giving time a plenty for mistakes and restarts? I have no grand plans, just a small rack with room for three to five tubs, which may go unfilled until I find the perfect ball pythons and feel I have the experience for them.
