I'm not sure if it would come under the same classification as a Pace or a
Weller, but I've got an Antex 660TC (the one with the temperature-set wheel,
not the one with the display - that's the 690SD).

I think mine's a 50W. <quickly checks>. Yep. 24V, 50W with temperature
feedback.

Amen to that. I tried to repair a Jupiter Ace with an Antex XS (25W, no
temperature control). They're OK for tinning wires and such, but hopeless for
any form of PCB-level repair.

I picked up the 660TC when Maplin decided that ?130 was "a little too
excessive" and dropped the price to ?60. I only ever use the XS for tinning
wire or quick connector-resoldering sessions. If it's on any longer than 30
minutes or so, it hits about 400C. If the bit isn't secure, it'll go right
up to 490 and blow the element. Thankfully the 660TC doesn't do that, and the
iron (and cable) are much lighter and thus easier to grip.

Next item to buy: a proper fume extractor or similar.

Later.
