I havn't bought them, but thought they looked cheap.
I am selling all my Grolsch Bottles on Ebay ATM
A bit late notice as it ends tonight but i only just remebered this thread!

I only just set my keg system up, and I remembered I had an old joystick in the shed.
This is how it turned out...
Looking for a James squire one for the other side if anyone has one to sell.
