I got my offset cylinders from www.worldofbrass.co.uk Super service.
My "local friendly locksmith" wanted 25 pounds per cylinder...

Hum, ISTR mine wanted something like £5 per cylinder -- can't
recall exact cost, but having a cylinder repinned to fit an
existing key was something like a couple of quid extra.

Sounds like you've got a good one there but I would have my doubts about
using a cylinder on my own house that could be got for a fiver. Zone 6pin at
about a tenner on-line is about as low as I would go.
