Not looking to part with more than £100 if possible, as I've bought/sold a set for less than £100 in the past, albeit they're rare to come up for sale. (Wish I'd held onto them now!)
Those that can, fit. Those that can't, store them and don't use them!
I've emailed a number of breakers so will see what turns up. There is one on ebay with a big old crack in it, but 10mins of googling doesn't exactly inspire me to think it could be repaired to as new condition with any amount of epoxy and polishing :thumbsdown:
