contrary to cadmus26, I can taste a big difference in margaritas (but I drink them straight up no salt). If you are mixing in a blender with ice and margarita mix go with something fairly well priced. I know what is crappy and I know what is good, but I don't know in between. I'll ask master, and maybe ironroot will post, because he knows such things as well. However I would not go with the "cheepest" thing, because you will taste it if it's really, really bad.
