bitmain is good? they have s3? i thought antminer s3, not bitmain s3
what do i buy to mine vert and drak?
Ummm... Antminer is the series of products, manufactured by Bitmain. So it's AntMiner S3 by Bitmain. It's good, cheap, power efficient, standalone, but the downside is that you need to get a power supply for it.
To mine VertCoin or DarkCoin (if that's what you're asking), there are no ASICs. You can build a rig of GPUs to mine them if you'd like, but GPUs consume a lot of electricity.
