Flat Broke? If you are flat broke and want to try mining at a very small scale you can take a look at the CoinFactories extension for Chrome. It's free to use and will let you try out small-scale mining to learn a bit about a hashrate, throttling, etc while you figure out your more serious plan. It's not a replacement for full mining but can be a good way to dip your toe into the pool without risking any money yet.
