US$180 or so is ball park for top quality chain & sprockets. DID, EK, RK, JT, Renthal, Regina are all very good. Lower tier but good value are the chains from the big wholesalers...Parts Unlimited, Bike Master, WPS. Pretty sketchy are the o-ring no-name chains off eBay.
If your chain has some stiff links, or lets you pull the chain away from the rear sprocket at the 3:00 position, or has red rust dust coming out of the rollers, it's time for a new one. Generally it's wise to renew the sprockets at the same time; worn sprockets wear a chain faster.
The DuPont yellow label chain lube is OK. The blue label stuff was weakened a couple of years ago and is no longer recommended for chains.
