ok, i can help you with a diy vape that wont burn it. take a 60w bulb and a socket, and a mason jar...

you cut a hole just big enough for the socket in the mason lid screw the light bulb in, and cover it with tinfoil. fashion a aluminum bowl to sit on the bulb. poke two more holes in the lid for air lines, and put weed in the bowl, screw the jar on, plug it up, viola!

ghetto vaporizer and it absolutely wil not burn. just make sure you don't use any higher wattage than 75, i prefer 60, make sure it's incandecent...

here's a pic...
