You can often find wheelsets on sale for 100ish dollars at nashbar.com and
other sites. If you can drop your brake pads 3mm or so, get 700c wheels,
since those have a better tire selection. You'll have to respace your
dropouts unless you can find a wheel spaced for an older dropout. You can
probably just spring it apart. Sheldon Brown has an article on this, I've
done it. Freaky, scarey, and quite easy.
You'll need a cassette of cogs. I like the silver Sram for 25.

Again, try Nashbar--I'm extremely pleased with the house brand prima plus
2's for about 10 each. There's always something decent on sale for that
amount.
Quoted message said:Derailleurs
If your old one works, keep it, it will shift much better on a modern
cassette and chain. Otherwise grab a sora, 20 bucks, or 105 derailleur for
35 or so.
The front should be fine, or get a new one for a ten spot.
Quoted message said:Shifters
Do the existing ones work? You can use the old friction kind with a new
derailleur just fine. A set of Shimano downtube clicky shifters will cost
you $30. Upgrading to STI will cost a couple hundred just for the levers.
Eek. If you want STI, get a new or used entry level bike. 😉

Cheap :P
so to add up:
100 wheels
20 tires
25 cassette
10 cables
30 Sora derailleurs
30 new clicky downtube shifters
which comes to $225 bucks, and you'll have basically a new bike. Go for
it. 😄 When it comes to moving bits. I'd skip the derailleur replacement
unless it's trashed and see how the old one works with the new parts. My
1979 Shimano Titlist (pre 600) shifts great on a new cassette. Gears just
"pop" into place virtually silently.
