Seconding Dusty on Herpcult. I personally prefer front door glass enclosure from Exo Terra (they glass doesn't deform over time, doesn't scratch and doesn't fog or turn yellowish). This said, out of all the different acrylic enclosures I also have, Herpcult seems to me to be the better ones and best made ones. My favorite features is how well they stack up which makes for more Ts in small places
