Hey captain,
That's funny, I originally ordered the Twin off of ebay, but the seller screwed up and sent me the dr90 instead of the dr90Twin. Because of that, I eventually ended up getting a DP90 3x2x2 propagation tent too, but I haven't even taken it out of the box yet because I don't really know what kind of lights I will use in it. I like the tent though- the material feels heavy duty and it doesn't leak light. Some people complain about the plastic corners, but they seem sturdy enough to me. I really wanted the Twin though because I liked how it was set up.
