Come back for a second to see if this place still exists and there's a smoker thread so I had to chime in.
I've had the Weber smokey mtn for 2 years now. I've enjoyed it, but it has some things to know about. It's a water smoker which means there is a big bowl of water (~ 2 gallons) between the fire and the food. This is critical to regulate the heat in the cooking area. You absolutely must keep the water level in a good place during the entire smoking event to keep a steady 225-250 temp.
One thing to point out: adding water to this smoker midway through your cooking process is a huge pain in the ass. There is little to no space from the access panel to add water, and you certainly can't dump it over your food. The best way I've found is to take a dustpan and use it as a funnel to route water into the bowl from the side access panel, or use a ketchup bottle to squirt water into the pan directly. Do not add water while leaning over the top of this grill. If you happen to splash or spill water onto the fire you will have a steam flash that can cause serious injury, and people will make fun of you.
Other than that this is a fantastic smoker. 125 briquettes or equivalent amount of charwood will burn steady for 4 to 6 hours, sometimes longer, while adding wood for smoke along the way. I'll usually throw in a few more chunks of coal as the day goes on as needed. The smoker takes up very little real estate on your patio since it's so vertical. The temperature is super easy to control with vents and the water pan. there are 2 18.5" cooking surfaces. There is even a fan site
http://www.virtualweberbullet.com/ with recipes, tips, tricks, forums, videos, etc. The recipes there will often have time tables on when and how to set vents, water levels, turning food, etc.
$300 is what I paid on amazon a couple of years ago,
http://thetracktor.com/detail/B001I8ZTJ0/ says that's pretty much what it costs most of the time with some exception in fall 2011.
If you are seriously in the market, I would recommend this smoker. It's quality.
