They were pretty cheap if i remember too..
I also remember my lady DRAGGING me past them, whilst muttering something about living in a g'damn greenhouse. lol.
Monkeeman, why not try to pick up a 'drobe at a local yard sale?
I got a PC hideaway cabinet for a buddy of mine, that is gonna be converted into a mini growspace for him, it was only 30bucks.
