I've heard nothing but good things about the DS4, but I've heard a few people complaining about the DST (the swivel's not needed, etc etc). I'm definitely planning on getting the DS4 soon myself, if that helps.
Pick up the phone. You'll get it way cheaper than online. Try Divelife/SDS as they seem to be knocking them out cheap on a regular basis.Hi
Thanks guys - looks like the weight of opinion is coming down on the side of the DS4 - which is kinda where my DO was going anyway. I'll just go and have a search for some prices now (( - it's only money (hopefully the wife won't find out!)
