Which is better: Samsung galaxy mini, galaxy fit or lg optimus one?

Question is pretty self explanatory, need to buy a cellphone help me choose one... only these 3 so please don't suggest any other phones... I live in colombia so most mid to high end phones are ridiculously expensive... hell the iPhone is $1000. We also don't have brands such as HTC or Nexus. I'm looking for a good, not very expensive android phone that is overall pretty good, since android itself is a very versatile OS i think that the feature department is pretty much covered by all 3 and are pretty similar i their technical aspects. these are pretty much the phones i've been looking at that match my standards/needs (and budget :P)... thnx
