...But there are a few other options: he's replacing the expensive part and keeping the cheap,
consumable part. Have you considered going for an 8 or 9 speed shifter, and upgrading? You have two
options if you choose this route:
-buy a new shifter, cassette, freehub body, and maybe an axle, and convert to 8 or 9 speeds.
-buy a new shifter and cassette, and convert to what Sheldon Brown calls "8 Of 9 On 7", or using 8
of 9 speeds from a 9-speed cassette, and placing them on your existing 7-speed freehub body.

Neither of these upgrades is trivial, but they both come to mind because the shifter is usually the
most expensive part of either upgrade, and you're already definitely doing that.
OTOH, there's nothing wrong with a 7-speed, so don't let my delusions of inadequacy cause you to
mess with a perfectly good bicycle.
