Hi Tim
Not planning on performing 'Pineapple Surprise' or 'Peaches' are you :-)
I had trouble finding ours, most cans seem to be ring pulls nowadays. Ours is a cheap white plastic jobby marked 'WL Housewares' no idea where it came from but it seems to work OK.
Lakeland do one appropriately called a 'Magician Auto' which has a good write up and a lifetime guarantee for £8:99 - worth a try, most of their stuff 'does what it says on the tin' so to speak.
There's a Lakeland at Bluewater.
