Shower thermostat broken - replacement does not exist anymore?

[fredz]

We have this thermostat above. No hot water anymore... Local plumber says this system doesn't exist anymore and must be taken out, a new thermostat+shower head etc. installed, and the shower retiled. Sounds a bit harsh to me. Any one know a quicker/cheaper way to solve this? Or a plumber which has this in stock could contact me as well... (London)
