I can't speak to sous vide and how it turns out. I have friends that swear by it, but seems like a specialty thing where it is harder to make large quantities of food. I'll let Baldkin sing its praises. But that isn't grilling or smoking, so I'd probably go there after figuring out what you want for a grill. From what you are cooking, it sounds like you want to grill, not smoke. So you probably want a Green Egg or Weber. Either of those will handle charcoal grilling well while still allowing you to do intro to smoking stuff with indirect cooking (poultry or smaller roasts). I have a Weber 26" charcoal grill with grill "wings" you can lift and add charcoal without removing the grate for longer cooks like a turkey. I've done longer cooks like pulled pork on it, but it is annoying to be feeding it every hour. FYI, I've had my weber grill for about 20 years now. I've replaced the grate a few times and the ash collection system once. I used to put a cover on it, but it really doesn't need it. Just a really simple well-made product that has stood the test of time. From what I've heard, Traeger's are not great for grilling, wonderful for "leave it and forget it smoking", but don't leave a strong smoke flavor to foods (none of the pellets do). But I don't own one. This would be the high-cost "easy entry" to smoking. I personally have a Pit Barrel smoker and have heard good things about the Weber Smokey Mountain. I love my Pit Barrel for its simplicity, but everything hangs so if I smoke a large quantity, I can't finish it on the grate when the meats get very tender. For most things it is great, but occasionally it is annoying. Right now, I'm looking into the Chargriller Gravity Fed 980. Just don't waste your money at the big-box store cheap smoker grills. They tend to leak and you will fight them tooth and nail to keep them at temperature. I'll do anything from burgers and brats to pulled pork, ribs, brisket, and hot-smoked bacon on my setups. I've cooked enough pulled pork for a picnic of 100 people or so (32 lbs) at one time. I'll also recommend amazingribs.com as my favorite website. They'll do product reviews, but also lots of recipes and coaching on how to get better at grilling and smoking. Welcome to the family!
