SJS are just down the road a bit from me.
Some things they are a as cheap as chips; I bought a 110mm Ritchey stem for £4.99 and they have some 1 1/4" Control Tech quill stems at next to nothing too.
Just a matter of comparing prices; I recently bought some Shimano road shifters from Ribble, as they were £40 cheaper than crc. Doesn't mean crc are thieves, just means Ribble were cheaper on that item.
