Local craigslist ad has a char-griller smikin pro with sfb new in box for $75.00. I'm sure it's a good deal, but I see there are a lot of mods to get working realy well.Does anyone have details on the mods. Since I don't have a smoker right now and I'm using a modified kettle grill, This seams like a no brainer. A little more than I have to spend ( limited funds right now) I think I should jump on this. Thanks in advance for the input.
