Haven't really considered it. I haven't had any problems with meat drying out on me in the smoker. Just had the issue with the last brisket not getting smoke on the side with the fat cap.
I've found Kincaid's are in line with most other prices on similar cuts. You're not going to run into a situation where you're paying $3.99 at Marsh and $8.99 at Kincaid's for pork ribs. And, generally, the quality of the product from Kincaid's makes any extra $ you fork over well worth it.
I've got one of those grill/smoker combos that's just big enough to do a couple of racks of ribs or a brisket at a time. I usually use apple to smoke, as I have a source for a fresh apple tree that I cut parts from and let them dry for a few days. I find it imparts just the right amount of flavor. I don't have an issue with using mesquite, but I generally only buy chips to add to the charcoal when grilling.
As far as smoking, I keep my smoker between 200 and 225. I dry rub my meats before dropping them in, and I mop them with liquid. The dry rub and liquid mop are home made and secret recipes, but I suggest experimenting to come up with your own. Most commercial rubs and liquid mops are no match to your own blend.
Keep the meat moist, and keep adding rub. That's one trick I learned from my studies at smoking meat. You don't have to rub it in every time, but keeping it on the meat keeps the flavor added.
I can smoke ribs in about four hours and a brisket in about six. Of course, my smoker is smaller, so there's just the right size to keep the heat circulating without wasting it. I never use foil until I'm ready to store it in the fridge, and I've only ever used the oven to warm it up later.
Oh, and it's personal preference, but I don't ever add sauce to my meat while it's in the smoker, or on the grill. Sauce can be added when you eat it.
