About a year ago I was looking for a waterproof case for holding a mobile phone. The 50 Series Universal Hardcase from Tactical Tailor looked good, but is hard to get in Australia. Recently I came across the Witz Phone Locker, which appears similar. However, they do not appear to have as rugged clips as the TT. This size case would also be suitable for large MP3 players and smaller hand held GPS units . Most of the other Witz cases do not have belt clips (some are transparent, which would be useful). Also keep in mind that the dimensions given are of the outside of the case and what you can fit in them is considerably smaller.
