i need a cheap waterproof camera

I looking at getting a cheap waterproof rugged camera for around £100. i wont need it till may time so i have a while to decide. i been looking at Panasonic DMC-FT20EB-R which i can get for £100 tho i do like the Pentax Optio WG-1 but thats £150. anyone recommend another that will be good for the price? i like the Pentax as it is 35mm equivalent 24mm - 140mm where as the panasonic is 29mm - 108mm
