Yeah but you can get a steely 0.8 for maybe 30 quid on here. If you're desperately broke that'll do and it's not a huge waste of money if you need a back-up (eg fill nipple gets stuck or if you're reballing and the dive tank is empty).great setup you are thinking about but the advice i would have liked would have been getting a 4500psi 1.1l air system as you will buy one of these anyway. i regretted (sp?) getting a steely but hey you live and learn lol.
Have fun starting and welcome
