Hello Rose,
Welcome aboard. The folks at BBQer's Delight were kind enough to make an offer of a free package of their product to a mailing list I was on a few years ago. They sent me a package of their apple pellets. I followed the directions, and they gave a light smoke for about 20 to 30 minutes. Not really enough smoke for my purposes, I would have needed 2 or 3 packages to get the smoke I wanted in the ribs I was cooking. I can't remember what they cost, but it was enough for me to think that 2 or 3 packages per cook was too much. Plus, quite frankly, there is a part of me that didn't like cooking with something that looks a little bit like pelletized rabbit food.
Bottom line, give it a try. They do offer some woods that are hard to come by for the average person, orange and hickory come to mind. I just think that for general usage, it is expensive. I will stick to my hickory chunks.
JMHO
