Tap ceramic cartridge sizes

I need to replace the ceramic cartridge for a sink tap, but I'm having problems finding the right size replacement. I've tried taking the cartridge to a local plumbers merchant. They told me there weren't any standard sizes, and it was best to buy a new tap. They would, wouldn't they. I've had a look online, and there do indeed seem to be a huge range of different sizes, some with only a millimeter different between them. For example, look at this table for cartridges with 20 splines and 3/4 BSP thread, which is what mine looks like: There's more than twenty types, and some of the dimentions are so close as to be indistingushable using a ruler. What's worse, none of them actually correspond with what I've got - my cartridge has a maximum diameter of 28mm, not 30mm. Does anyone have any pointers, or is it really this difficult? Do people generally just replace the taps nowadays? It was so much easier just replacing a tap washer on the old-style taps!

Yes, it just happens I have a suitable box spanner in the plumbing bag - for undoing back nuts;

Temperate Heating had what I needed, and I've got the tap working again now.

So thanks for the recommendation. Saved me having to buy a new tap.
