This may be already known, but cpooutlets.com is selling either the DEWALT DWS780 or DHS790AT2 Miter Saw with a free stand (either DWX723 or DWX726) and free shipping. If it has already been posted, then I will delete this as I don't want to ruffle feathers.
Reviews for the DWS780 are good enough that I bit. Many people I know have DeWalt miter saws (this specific model as well) and they all love them. There is always a bell curve of people who love them and those who hate them, but this one seems that most love them. I didn't have to pay sales tax either; my subtotal was $549.99 (tried a bunch of different codes as well but to no avail)
Edited: Price shown as "$549.00" instead of "$549.99"
