After having read the thread, doesn't sound like you have the patience for the long, slow charcoal, etc process, nor the money for big investments on smoking equipment, which can be quite expensive, and, quite honestly, very infrequently used. Depending upon what you are cooking, why not try a product like Liquid Smoke. It's used in many restaurant chains to provide that smoky flavor for many applications. You can simply determine the right mix of Liquid Smoke, water, and any type of hardwood balance you'd like, pour it into the bottom of a 2-3 inch pan, bake in your oven to how you desire it, with meat on top of the liquid, separated by a rack of some sort. Then you finish it off on the grill you have. You can even hold it for a day or two before grilling and serving.
