Thanks to all who offered, I have now found what I wanted
I require a modern chainset, Deore M590 level or similar (could possibly go up/down a level depending on price), preferably in black, or with black rings (to match the rest of the bike
).
If it's not square taper compatible then I'll be looking for a BB too.
Must be reasonable condition, although does not need to be NOS or anything!
Not wanting to spend a vast amount (ie under £50 as that's what a new Deore chainset & BB goes for on t'bay).
