Welcome Tacorican... You have joined a great site. Folks are always eager to offer help with recipes, methods, tips, etc. but remember, there are as many opinions about smokers as there are smokers. You said that you have a budget. You also need to decide if you want to use wood, charcoal, propane, electric or whatever. Then decide the type of smoker will suit your needs. After that, try to fit quality into your budget and get the largest unit that fits. You can always use more room.
Good smoking, Joe
