I just clicked on the SJS link and searched under handlebars and they do ritchey risers for £14.99, Chainreaction have Brand X risers in the sale for £9.99. I'm sure other companies will do cheap risers too if you search around. Mine started life as 2nd hand RaceFace ones, I removed the black anodising with the most caustic oven cleaner I could find (wear gloves) and some wire wool.
