From $100 - $175, depending on the finish, plus shipping, which can be up to $75 more.
Hard chrome is the way to go, if you have that option -- its the most durable finish, and "slicks" up the internals, too.
Nickel is very good, and there are a number of space-age polymers or similar applied finishes (like Metalcol or Roguard) that are very good.
