So lately I've bought a few miners mostly because this is simply a hobby to me and somewhat of a learning experience. The miners I have are 2 BFL Jallys (7.50 to 8.50GH) and a BFL single 50GH miner. I have been thinking about getting an S2... Thoughts?
Why do you want an S2? Out of the bitmain lineup, why that unit?
You are getting ready to make a real jump. Running XXGH when you move to XTH shit gets real (fun). In your shoes, I'd read a lot and ask some pointed questions. When you get to "this makes sense because ______" throw up your idea. You may get invaluable input without wasting money.
