Just want to mention that the specs of that copy don't come anywhere close to the real thing. The international version is equip with a 1.4 quad core processor with 1GB of ram while the US version get's a 1.5 dual core processor and 2GB of ram. You should be able to find a used S2 or S3 that would fit your price range.
