Hi chaps, I got hold of a Canon Digital IXUS 500 underwater housing and am now looking for a used Canon Digital IXUS 500 camera to go in it ... looking on the auction site there are dozens for sale but 90% are 'broken - for parts only' ... is this camera worth buying or is it rubbish ? Many thanks for your time ... Roger (I snorkel on only a few occasions a year so it's not going to get a lot of use .. though I could use it as a PAS on holiday)
