So I plan to use my new camping stove at the beach on Christmas. It's one of these jobbies http://www.kathmandu.co.nz/camping/kitchen/gas/gasmate-3-burner-deluxe-yellow.html


 It doesn't come with a regulator, only a hose fitting for a 3/8 BSP LH connection. Because of this I merrily went and bought a 2kg bottle from the warehouse. 

Now I can only assume this bottle is filled with nitrogen as harking back to my gas station attendant days, new bottles had to purged of nitrogen first and weren't actually filled with LPG due to shipping restrictions.
This brings me to now, where I've discovered it's almost impossible to find a place that fills 2kg bottles!

Question 1) Anyone know anywhere on the shore that fills 2kg bottles?
Question 2) If not, can I just buy an adapter to fit my BBQ's 9kg bottle? Or do I need a regulator as well because the pressures are higher in a 9kg than a 2kg (I would have thought they would be the same)? 

Cheers!
