I'd say look into making a Gravity Bong.
I personally own a portable vaporizer called which is rather expensive,
but hits great and is in the end worth it because it comes with a 10 year warranty.
When I was new to smoking I used a Piece or a Homemade bong out of Gatorade bottles or other household supplies but
the best possible Homemade bong I've used is a Gravity Bong using a 2 Liter Soda bottle and a bowl of water deep enough to submerge most of the bottle after cutting out the bottom. You light the top then slowly pull up and the inside of the bong acts as a vacuum keeping most of the smoke inside until your ready to hit, definitely worth looking into if you have a very small amount of herb or want to get really high.
Here's a link on how to make one http://www.youtube.com/watch?v=gmkwE8wh_jI
