: Dewalt 423k which I believe can accept different brands of sand paper
: attachments. Thanks

Not sure what you meant by sand paper attachments. If you mean sand paper itself, then no, it's not true. I have the Porter Cable 333 (fixed speed) and use third party sandpaper just fine. If you are talking about special backing disks, then I'm afraid I don't know. I haven't bought any attachments for this sander. Sorry.

There is a great discussion in the archive that you should look at if you haven't seen it already. About a year ago, I asked what sander I should buy, and got a lot of feedback.

For what it's worth, I'm really pleased with my Porter Cable 333 sander. I would have gotten variable speed, but Home Depot didn't stock it, and I had gift cards for Home Depot, so I was sort of stuck. The fixed speed is real good though.

Hope this post helps a little.
