You can borrow mine, but you'll have to come over to Dallas to pick it up. By that point, you'd be better off going to Home Depot and buying one for $12.95. If you have to reroute ABS lines, you'll need a 3/4 inch hole saw, too. Also, a metal punch makes starting the holes much easier, but you probably already own one.
Good luck with the install. It's a PITA, but fun once you're finished.
