You're not likely to need a complete set: they can be replaced individually. Mine is from about 1987, and I got it about 10 years ago on eBay. I've replaced one element card, as a result of a previous owner's dodgy repair causing arcing that eventually burned out a connector. The others look very old and are still fully functional. Having said that, I understand the clockwork timers also fail from time to time, and they aren't especially cheap. And the toast, while very good and continuously adjustable in hue, isn't quite magnificent.
