I could never get into those volcano type things, they're rather undignified and a bit 'glue sniffer' what with the plastic bags and so on
I do have one of these, though:

herbalizestore.co.uk/products/arizer-solo-2-vaporizer

I never use it because they are rubbish for hash, but it's a great piece of kit
