About 3 years ago I cut a side box off a three box tray from HF and used the soldering gun to cut/melt some slits for the tape roll to sit in the back box, feeds through the next box with the compound in it, very similar to the one linked, except mine was $3.99. Used it for years repairing drywall in fixers with 20 min. mud., much faster than my trowel/knife for ceilings/walls. Use 90 min. for that size room, second coat with hot again, third with drying type, no sanding. Then I bought this last year, use 40 min, takes a little longer to clean, made a corner nose-piece from door brass kick plate, interchangeable; http://www.amazon.com/Homax-6500-Dry.../dp/B000ULBC6K Absolutely no complaints... it is fast;
