Granted, I'm new, but I think I've worked out a strategy.  I ran the math, and the erupters will pay for themselves in about a year - I know this.  I'm re-investing the BTC into GHS at cex.io and back into themselves.  I realize that there's a lot of people ahead of me right now, but that's how it is when you jump in like this.

I've also yet to find an exchange that I'm willing to trust enough to actually buy bitcoins.
