Living near Dover, I've been popping over to Calais from time to time, to buy beertender minikegs. All continental beers of course, but pretty good value at ��ã8 - ��ã15 depending on the beer inside. Converting them for my brew took some trial n error. But I think I've now figured it out. Been using them for 6 months without any real problems. So, if anyone has them, don't sling them out they can be converted. They come with a top tap and can be adapted to take CO2 via a S30 valve. The internal gas charge unit can be removed by cutting a 42mm (roughly) hole in the top and then filling the hole with the top of a PET bottle glued in place. I use lucozade bottles because they have a wider neck. Easier to clean inside and the S30 valve can be fitted into the bottle top. Despite some reservations I use araldite rapid to glue the bottle top, but others are available of course. Not been poisoned.... yet.! I know most folks won't be using these, not visiting Calais much, but just thought l'd mention it....
