Query: Searching for an Effective Spanish Language Course

I've been searching for a Spanish language course that is effective. I became disenchanted with Pimsleur. I heard from relatives that Rosetta Stone is not as good as its high price warrants, and that Berlitz seems to offer the best language courses. I think for its price it is very helpful, but it is too soon to make a judgment on its overall effectiveness.
