I gotta say, this is one that I have asked for and been asked for many times over the last year. A kit with all of the best from Poorboys in one box. Considering a PC and flexible backing plate as ONLY items needed to make a flawless finish. (if you already got them, you are ready to go)

And forum discount makes this a great deal, considering that the original price alone is pretty darn attractive.
And for those of you still on the fence in buying a PC (Porter Cable 7424) as a complete kit ready to go:
