Psp Go? or Psp 3000 which should I choose?

Im deciding which I should get, a psp go or a psp 3000. I could be patient and wait for the psp go or I could just get a psp 3000 right now. My actual goal is to get all three handheld gaming systems of 2009 my roster consists of -Dsi -iPhone 3G (soon to be iPhone 3Gs) -Psp Go?, Psp 3000. I just don't know which psp to get for the sony side of my list. I don't want garbage like: "Oh the psp go is junk because its smaller then psp 30001111!!!!!1!1!oneone remember size matters 8======D"
