There is a ton of them out there, and it is just a matter of opinion on what is good and what is not.
I have found, just my 2 cents here, that if you can get a local made one, and then try it straight first, then try a couple of modifications to it, you will get good results.
Try one, and then if you want try some fresh ground onion, a little garlic, etc... than if you really want to get adventursous try a couple of spices... depending on the meat you are cooking, be careful doing this mod... sometimes, a little will go a long way, or just the opposite, will clash with something in the original sauce.
It is all just trial and error....
Good luck.
