The superior Dr Pepper clone absolutely has to be Patriot's Choice brand Dr Blast. As far as I can taste, it is exactly like Dr Pepper, and you can also get it for a cool 25 cents a can. Unfortunately, just about the only place you can find these is at Navy Exchange, or NEX stores, which will require you to go on board a naval air station, or some other jointly run US military base. Furthermore, you can't typically shop at NEX unless you're in the Navy itself -- so getting 12-ounce cans out of the vending machines is pretty much all you'll be able to do. But, if you do have access to the NEX store and are a total Dr Pepper junkie, I would highly suggest trying to grab as much of this wonderful beverage as your pocketbook allows.
