gas supplies (campingaz)

sy melmar y <newsgroup@...>

on our maramu we have a (quite) small gaslocker just outside the galley.
it has room for two campingaz (blue, 3kg) bottles. has anyone experiance
on avarage consumption (how long will a 3kg-bottle aprx last?) and where
we will get campingaz (around the world). what other ways are used to
get to cooking gas are used? i wouldn't like the idea too much to tie up
one of those huge bottles to our pushpit... we are "newcomers"/just
starting our circumnavigation - thanks for any ideas/hints.
