Have you tried NLV's Caparillo Cafe Latte? I'm not sure if they make it anymore, but back when I tried it, it tasted like a frappuccino.
Another one I would suggest is Vermillion River's Caramelized Cappuccino.
I just ordered some Carmelized Cappucino for VR in my 6 pack sampler...its suppose to be the best out there
