i have just bought a radius arm reamer of a fellow mini fan dont no how much they are to buy new but i paid £50 for this one 
I made one a week or two back with a £6 reamer off Ebay, an old radius arm pin and an old front tie bar.
Genuine ones are rocking horse poo, last one I saw went for £76 on fleabag. But as said above you can make one up easily enough. For a proper one it’s a reasonable price.
The genuine tool to do the job properly is a lot more than £76…

Read the post ‘last one that went on fleabay’, no mention of it being new. I am guessing the one this guy has bought isnt new either. Somerford are taking the pee with that price. No wonder minis are getting expensive when people try to rip you off like that. I deal with a machine tool company at work and needed a reamer with a special tapered end, they made it bespoke for less than £160.
