Managed to get one. Looks cheap, but not too bad for 15 quid (ie buttons work). Chest thing a bit stiff and wasn't always reading consistently - might be linked and work if I get the position better. Does interfere a lot with others. If has rather too many functions though, some of which are silly- calories burnt - some more useful (lap counting stopwatch, beep outside zone , max heart rate etc.), but so many of them its going to be a pain to remember. Its also got quite a nice moudled handlebar mount, but we'll have to see if it interferes/is interfered with the wired computer.
