yep - honestly, an S7 will only make you around $100 a month right now, at the current difficulty. With the increasing network difficulties, it won't break $80 in the next month or two.
Would love to join a meet up, but Columbus is just a bit too far. You might consider joining the Meetup group - seems like there's a core group keeping it going, and also the next meeting is tomorrow:
http://www.meetup.com/Columbus-Bitcoin-Meetup/Thanks for the advice. I am member of the local metup group. My intent is not to just evaluate the best options for mining, but to
start a new business(s) with a group of people that already know about bitcoin. I have already started another company and have Ideas about new companies, but need some more talent. This is why I look at other Miners.
