Well I bet in a week bitcoin prices are back up a bit after the US marshall auction fiasco so they would be cheaper BTC. Also the rocket boxes are delayed to the same day, the 27th, however the rocket box does not come with a controller (Raspberry Pi ) and the S3 does. The S3 is faster hashing too. I can trust the S3 already because of the track record with the S2. I will wait patiently.
