How many of y'all have built your own? Pros and cons? I feel like it would be a fun project but what I am most worried about is getting the heating right (uth or tape?) and am I supposed to use a sealant in the back of the rack? I feel like I could do this. But I want to do it right. This is kinda what I wanted to go off of:

Let me know what y'all think or any advice before I get started (:
