For our sink, I used a pvc p trap, and one of the slipover clamp fittings to solve the problem. I have also used a metal p trap, with similar fittings, to go to the black abs, again with no problems. If you don't like the big box stores, Ace Hardware usually carries most all this stuff, they are more helpful than the big box stores, and the few cents more I pay for the "stuff" I need goes into a local merchant's pocket, instead of a conglomerate's bottom line.
