I like the "HandiPoints" site Bethany recommended. I just tried it and it was easy to sign up and create a chart. They also gave the ability to customize the chores (in addition to choosing from a list). The only thing I didn't like for your purpose, was that the image of the chore was rather small, and the stars/symbols next to that made it rather confusing when it was printed.
I have a chore chart that I use for my family in Excel or Numbers. It's nothing fancy... a simple chart, with clip art from Google Images. But it's worked for our kids for a few years. We attach it to the side of the fridge, so they can easily see what needs to be done. I have one chart for the school year (when their chores are separated into "Before School" and "After School", and another for the summertime. Send me an email at ____@____.com and I'll email you a copy if you'd like.
