Hi,
Just decided to move to mini kegs, bit of an intermediate between bottles and Kornies, bought 4 kegs and a CO2 pump from here http://www.candirect.de/ for £50 (cheaper than any uk supplier from what I can see), the kegs don't have any built in taps that can hinder cleaning or any silly writing on them.
Looks like they have a good collection of FV's with large screw on tops.
Seem to have a big selection of other steel kegs etc.
