Excellent start for product design
By Daniel J Dravis
I have over 15 years experience with drywall, so I'm not new to this. I agonized over spending this much money on a sander for a couple years. Yes, it's been available that long. But, I'm getting older and the back and shoulders don't like hand sanding on ceilings and I have yet to perfect the "sponge" method.
Regardless, I purchased the P-C sander and a box of 150 grit pads. If I didn't like it, I could sell it on "auctions". After one large room, I was pleased. I will agree with some other reviewers that you can make plenty of swirl marks. That's the first thing I did. The second thing I did was to spend 5 minutes playing with it to figure out how NOT to make swirl marks. It really isn't that hard. It is much faster than hand sanding and virtually no dust. My customers love that part!! (I do alot of remodelling jobs). If you do a good job mudding, there should be minimal sanding to do anyway.
This sander will NOT do inside corners. Based on its design, it can't get any closer than about 3/4" to the actual corner. Know up front that you will still need to touch up the inside corners. This sander is primarily for large relatively flat surfaces, and in my opinion it does a good job when used properly.
The other thing that P-C should work on is the weight. I know we all carry around tools that weigh more than 8 pounds. Try holding it over your head for any length of time though. While it is balanced nicely, 8 lbs. is still 8 lbs.
You also don't need to spend "money" on the vacuum either. (Sorry P-C) My QSP shop vac with a Cleanstream/Gore-tex filter($22) works just fine.
The 13' hose means you can put the vacuum in the center of a room and not have to move the vacuum, just walk around and sand.
So, don't look for mine on "auctions". It's staying in my toolbox.

PC 7800 is a winner!
By R. Cook
I am 60 years old and building our third and last home. We have just finished tapeing and bedding a kitchen and two baths and have found the sanding to be almost effortless with the PC 7800. We liked the hoop and hook 150 and 220 discs because they are so easy to change without tools. Get plenty of the 220 discs - they do not affect the paper as you are feathering in the taped joints and nail or screw bedding. We connected it to our 20 gallon shop vac and the suction almost holds the tool to the walls and ceiling. A smooth orbital motion takes care of any sanding, and then a touchup with a sanding block in the corners (1/2 inch out) finishes a room very quickly. What a pleasure to buy a tool and have it work as advertised. Thanks Porter Cable - and the other reviewers that convinced us to make the purchase!

By L. Angelo
I read a lot of reviews before buying the PC drywall sander. Needless to say, this is the best drywall tool purchase I've ever made, and the bursitis in my arms and shoulders think so, too. Being a remodeler and also doing repairs for several property managers, this makes for quick,easy, and clean work. I just attach it to my 8-gal. shop-vac equipped with a drywall dust bag, and a cleanstream filter as a secondary backup, there's almost no dust at all. It took some getting used to, but once I got the hang of it, it leaves very little swirl marks. Like some of the other reviewers said, don't push it and let the machine do the work. Since I haven't hung more than 40 4x12's in any one job, I've been using No-Coat to tape the inside corners and while it costs a bit more, it saves time because I can stay away from the corners, for the most part. What little hand sanding I do after the final coat, I use a hand or pole sander that attaches to a vac; found them at the local Grabber dealer. All in all, this is one tool that is worth every penny.
