you will not find cafe tacuba records since they were never released in Mexico. I asked a rep here I know and he recalls they were only produced for South American countries and in limited numbers. That is why when they do come up on EBay they are usually from Argentina, Chile etc.
Their recent disk however was available at a coupel of stores at around 25 bucks. from what I found there were 3 variants (black,cream marbled,clear). Last time I went to a local store they still had 2 cream color copies. I bought one only cause dude who was in charge of area did not know shit about records and took other copied and bent the jacket to shit.
