As a full-time remote developer I looked at some co-working spaces here in Richmond, VA. I can work at home just fine, but I miss seeing and talking to people. While I could afford the $250 a month. What I was getting was a noisy environment, thats about it. I much rather put the $3,000 a year in an IRA , vacation or just about anything else.
I think a meetup for remote workers once a week is probably best for me. I just haven't had the motivation to build that that :-/
