car repair, quick answer needed

Auto repair place is suggesting replacement of distributor cap and rotor. Is this a relatively easy repair that I could do myself? What's a reasonable price to have them do it?

Thanks!

Really ticked at Mr. Tire

My Saturn is 13 years old, about 230,000 miles, and running pretty well, considering I've spent next-to-nothing on it for the last two years. Just oil changes and gas. Oh, and a few bucks for an air filter.
