is this worth it? someone managed to make roi on those? how much the earning before you throw it on the wc? i was thinking of buying one

Are you kidding? the s3 has been around a few weeks only, and ROI takes over 100 days, just use the following calculators:

This question will be a proper question by the end of the year.

If Bitmain changes to their old selling model, and decides to go to sale from stock instead of pre orders it may help a little, since instead of having to wait 1 or 2 weeks, you will only wait 48 hours for shipping.

The pricing of the S3 is so that it barely ROI, most others do not ROI.

And if for some reason bitcoin price drops the S3 goes up in price and you will definitely not ROI, at the beginning of batch 5 the price was 0.64 then it went up to 0.68, now it is at 0.66, however difficulty has continuously gone up during this period.

I am waiting myself for the price to drop, the ones that buy independent of ROI will not ROI but will enjoy the fun of mining, the ones that wait will enjoy double fun ROI and mining, and who knows if during that time a better deals appears.

The next best deal seems to be the sp30, however that is a pre order of 1.5 months maybe 2 months until they change their model of sales it is a worse option, however if the start selling from stock it could change things a lot taking into consideration that the power supply it is already included, in such a case it is easy to compare just plugs numbers in the calculators and see which ROIs first.
