The one I'm looking at is a simple standalone one. I was considering the kind that attaches to a door frame but I've seen too many Fail Army videos of those not working out well. : ) The area I plan on using it in though is our staging area during the remodel so I'll have to wait for all that stuff to be cleared out. You definitely have my vote. I was going through and trying to remove my votes from inactive witnesses the other day but it wasn't working. I'll try again today.
