Afternoon experts, newbie to mining.  I have Two (2) Antminer S3's and just purchase Five (5) Neptune KNC Miners.  My total investment is under $300.00, so want to see what I can achieve this this.  I have heard that Antpool is a fairly decent Mining pool to join, but welcome any recommendations. 

So my question: 

1. Has anyone ever tried the Neptune Miners, and what was your experience with them? 

2. I have read alot of Antminer, so curious to see how the Neptune Miners compare?

3. Can different Miners belong to the same pool?


Thanks

TF
