Agree.  At the level your looking to get in this is a hobby not an income source or a solid investment.  But if you wanna try out mining and see how it does go for it.  I started mining about a year ago and fell in love with it even though it's not very profitable its a hobby that pays for itself at least and I've done pretty well and got a profit which of course I immediately bought more hardware with.  

I started with 2 S1s and have done well enough that I now have 6 S3s and a GAW Black Widow (The BW is on the verge of retirement) But I'm VERY lucky to have done as well as I have.
