Re: India next week !
theres plenty of stuff around. loads of underground shisha places around Mumbai and a couple of good shisha places in Anjuna Goa. Cant remeber the names though, just found it while on the moped.
you can buy stuff reasonably cheaply, but its not as cheap as you'd expect compared to toher indian prices, and i didnt buy anyting as i had anohter 8 months of travel.
shisha places (the legal ones) always seem to sell shisha and hookahs. never saw any in the illegal ones.
