Hey there, I was very confused as to which to get as well. I met Jeff the owner of BOAPHILES at the Chicago show. Really nice guy, stands behind his work and now i am the owner of two of his 5 drawer side ways racks. I got those so that i could do smaller bins on the bottom for my younger snakes and the bigger drawers for the larger ones.

I bought also bought the Themostat that is on his web site. No issues, easy to set up. Instructions came for everything. I did punch a hole in one of the bottom smaller bins to run the probe into it. Temps are perfect.

My two cents..
