Changing drag washers is something that the average person would be able to do themself. You can obtain all the parts you need from John's Sporting goods in Everett. He is the N'West repair guy for Shimano. It looks like you live the OP so you'll have to order all your parts. Be sure to buy several sets and get the grease as well. The procedure is like any other mechanical preocedure. Disassemble (remembering order) and put back together. Having two reels is a bonus because you can look at the other for refence. If you think you want to tackle it yourself, let me know. I can post something with a description of the actual procedure.
