I was wondering if the porter cable 20v max are any good to buy. I am considering these and dewalt. I am leaning more towards dewalt, because i do know they are contractor grade, and last a long time. I have had no complaints with my 18v xrp. I have had the whole line for about 10 yrs, and they are still going strong. But it is time to upgrade, and with dewalt i love em, but the price is a little much. So, I have been looking at porter cable, and the 20v max looks nice, and they look of quality. But i really never new to much about porter cable, never owner any of their tools. Are they worth buying. how is their quality, how are the specs? Would it be worth it or just stay with dewalt and dish out the money?
