Hi Folks,
 
Have the option of picking up the following:

Average : 220 to 230GH/s  at the current rate(0.013 BTC) per hour.

1 x Bitburner Fury 50GH/s Mines between 50 and 52 GH/s

3 x Avalon Mini Miners.. 60GH/s each, Built in WiFi, LAN, Web-server, Built in CGMiner computer, Firewall.

Price 2500

Worth it? Is it a good idea to start here with mining? Any idea what the ROI would be (rough estimates will do).

Thanks in advance
