| I will dig on the web but am sure Draeger officially extended the run time for warmer water for the dolphin recently...
I think everyone will extole the benefits of full CCR over SCR and the Sport Kiss IMHO is the most cost effective unit out there, however you could get a Dolphin SCR second hand via ebay for a song and a dance $1k to $1.5k the only thing is I think if you get a Dolphin you will realise Rebreathers rock and then buy a fully closed one!
