Cheers guys i'll be mooching the web tonight at all of them. Woz i keep getting told the xtx50 is great, don't quite understand the DST and DS4 stuff though. The only reason i said XTX 200 is i read a great review of it in diver mag, It's shiny
and its er shiny, people kept saying buy the best you can afford and for the bit that my life depends on i figured the expense is worth it. I am however prepared to bow to peoples experience etc the only thing that puts me off the 50 is that's what the club uses and i'd be afraid of mix ups and stuff.
