I think 2 bucks a piece, the trip adapters were like 4 a piece. Got em all at Lowes. So, I dropped like 45 on it. It's perfect for a cab. Speakin' of which, all aspiring stealth growers stop by your Big Lots. I bought a 31"w x 31"d x 33"h corner cabinet with, WITH, a lazy susan inside! 60 bones man, and with a little work, i.e. weather stripping, lock mechanism, exhaust and intake, it'll be the perfect veg cab. It's going to be my project come June when I move. Don't want to set it up and have to move it, it's a good 60 pounds and somewhat cumbersome.
