I've seen the Bullet Shaped Brinckmann Smoke 'n Grill for as low as 40 bucks before and I don't think they ever cost more than 60. They don't maintain heat that well but I have used them with great success with pulled pork. I just smoke the meat for about 4-6 hours and finish it off in the oven at 170 degrees ina shallow pan wrapped with foil (a small amount of liquid on the bottom of the pan to keep the meat moist). Is it cheating? Sure. But it makes killer pulled pork.
As far as smoking sausage, fish, chicken and grain it works just fine without needing to put in the oven.
