I'm after some 20 Litre Sankey (UK, S) kegs. I've used corneys before, but I prefer kegs as I've never had any CO2 leaks with them and they are hard core thick steel that will last forever! I have 4 X 50 litre Sankeys, but a move to a smaller batch size means I'm happy to do a trade for up to a couple of the big ones. I have all the paperwork, purchased from Portinox a few years back. Or if you've any links to a good supplier, that would help too. Cheers guys.
