I purchased this from here. 

Paid £415.10 including shipping and license. 

If anyone is into this and interested, happy to part with it for significant discount than what i paid. I tried using it for a few days and did not see a lot of earnings and maybe my PFsense did not like the way it's trying to connect and do etc. 

Gave us and left it idle, happy to share my license code for it. 

Looking for NZD$ 500 ono - pick up from flat bush, auckland or can ship.
