The metmachex style swinging arm on the ZRX 1200R has thrown up an issue

The drive chain is looped through it and must be broken to remove.
I normally just fit a new endless chain when the swinger is out but that won't work here.
I can get one of these tools for sensible money -

But the other kind is about 4 times the price and I can't justify for a one off project.
So the question is -
Has anyone used these KM500 style splitter/ riveters and are they any good or one to avoid?
I believe the new chain needs to be 530 FB x ring 106 links for a ZRX 1200R if anyone can confirm please?
What does 530 actually stand for again and what does FB denote please?
Or does anyone near GL7 postcode have the better tool avail for loan?
That's all my chain thoughts for now.
Cheers for looking from Mark
