Blue Line Automatic Taper

What it's used for:

High-speed filling and taping of seams between drywall panels
If you do serious work around the house, you've probably dealt with drywall. Most DIYers tackle the seams between Sheetrock panels armed with a trowel, a roll of tape, and a bucket of gooey joint compound. Those people are suckers. Professional drywallers use automatic taping machines, known in the trade as bazookas, like this swanky $1,725 Blue Line.
