The Blue Meanie Vaporizer is fairly cheap at around £50 UK.
It is a basic 'soldering iron' type vaporizer, and does what it says on the box, however, it has a tendancy to get too hot sometimes. resulting in smoking.
You have to be careful to monitor this vaporizer, it works, but isn't the most efficient you can purchase.
It may be good for infrequant use, but not if your a regular user of vapor.
