I just picked up a 5 tub V70 rack from Chris at Cserpents and love it. My requirements went i look at commercial racks are pretty simple. V70s or CB70s over Sterlite 41 qt tubs, and the heat tape has to be recessed. I hate the idea of the tub sliding directly over the tape, that cant be good. I also prefer solid sided over the economy style for an insulating effect, I dont know this for a fact but I feel like the solid style will hold heat better. I picked it up at a reptile show whoch was excellent. Their were three different manufacturers at that show, so I could compare all there racks directly and pick the one I liked best. And I didnt have to put it together or pay for shipping!
Other then that it all comes down to price and lead time
I could have attempted to build my own, but I have several big DIY projects in the works right now and just didnt feel like taking another one on.
