Best of luck. I still haven't had a response from Divematics about buying an adapter to fit one.

So, am now in the hands of Mr Narked@90!

In a similar thread, I came down on staying with my Apeks ATX50 because a) it's Apeks and everyone over here rates them, b) it's quite small, c) I already own one so just need an adapter from N@90. I think the size will be the same as others in the ATX range so can add a higher model later if I need to.

If I wanted to buy a reg specially for this I'd be asking people how they get on with the XTX series as it's smaller and can fit both ways round.

Other people also rated the Poseidons, Scubapro and Mares Abyss.

HTH - do a search for the thread. BTW, people will always say theirs is best, which is natural. Find someone who uses both for a proper opinion!
