+1 for sprocket center, I got some good steel sprockets and a really nice DID chain for 200 bucks. If you do try it yourself make sure you have the proper tool to rivet the new link, I tried to cheap out on that and almost ruined a very expensive chain. I got the right tool and it was perfectly easy. Check ebay for the Stockton Chain tool, I got mine from a member on here for 50 bucks. In my experience you can get a much nicer setup than what the shop will put on for about the same price. GET EXTRA MASTER LINKS if you do it yourself, trust me you'll mess up the first one if you've never done it.
Also, with 30k miles on the bike the chain has surely been changed. Is the chain out of adjustment room, or does it pull off the back sprocket? Also do your sprockets look hooked or worn? My stock chain was done at about 15000 miles, but the stock sprockets were in perfectly good shape still, but I would recommend replacing both at the same time if you do.
I'd bet you could get a nice setup from sprocketcenter.com for $200, then find a chain tool for $50 if you look.
