I agree with the others - it is very easy to make your own rub - a fun way to experiment with flavors and the like when you grill or roast - if I am lazy I look to any of the great rubs at The Spice House - http://www.thespicehouse.com/spices-by-category/rubs
My favorites are the Back of The yards rub and Gateway to the North Maple Sugar Seasoning
I also make my own depending on what I want to end up with. Throw in some garlic powder, seasoned salt, herbs, Mrs. Dash garlic & Herb, and whatever else I'm in the mood for.
If I am lazy, or don't have the stuff I need, I use Durkee's Grill Seasoning. (They also have a mesquite flavor that is very good) It has a very good flavor. On the label it says "a blend of Parmesan cheese, garlic, onion, bell peppers, black pepper, and spices . . ." Just don't put too much on or it is too salty, unless you like that! We really don't like the flavor of bell peppers, but until I read the label I never even knew they were in there.
Another one is Grub Rub. It's very good, but a little sweet, but it gives you a moist, tender piece of meat. I got it at a sports store!
I don't even think thats necessary considering how easy it is to make your own. I don't have access to my recipes now, but I made one from The Best Recipe cookbook and it was excellent. I made it to put on ribs for a little "rib-off" between the hubby and I and mine won on flavor.
The recipe was very simple like chili powder, cumin, garlic salt etc.
