I have a Cookshack Smokette series (Residential Series) and love it.
Low and slow is the way to use a smoker and this thing works great.
Although a bit pricey, the cost savings of fuel compared to charcoal or lp will make up for it through the years.
I had an old brinkman and although it produced some good food, you really had to work constantly to maintain temperature feeding it all day.
I did pork butts last weekend and chicken tonight. Easiest and most consistant smoking I have done in the last 20 years. I just ordered a nice brisket for next weekend.
They also have a great website with tons of information and a great message board.
Hope this helps..............................
