You don't need the specialist tool to remove/install threaded headsets, but it does make things easier. A big adjustable spanner (or a viscous-fan spanner for a 1980s Ford Cortina... everyone's got one of those, right?) will undo it, and you can drift the cups out of the frame with a long flathead screwdriver and a hammer, or a bit of pipe and a hammer (the removal tool is just a bit of flared pipe anyway, I made my own).
Reinstallation just involves knocking the cups in with a bit o' wood and judicious use of a mallet, or you could use a G-clamp and bits of wood.
Retrobike is the most reliable place for getting old geared bits. They do pop up here, too. You'll find an excellent quality (531c throughout) frame for £75-£100, but really the Raleigh Ritmo is a decent bike - with mudguard eyelets, too, which is a good thing. A 531c frame would be slightly lighter and possibly ride a little more comfortably (skinnier tubing) but it's also more expensive, more prone to rust and much more prone to denting. The Ritmo is the sensible choice!
