I am new to the whole mining experience but have learned a lot from this site.  I have come to realize that mining bitcoin is not going to be very effective for me.  I have decided to mine alternate coins.  I am doing this for fun so I am using my laptop and if/when an inexpensive hardware becomes available to plug into my laptop via usb for scrypt I may purchase.  I will be getting a usb miner for the sha coins.  I know ROI is not very likely.  Can someone tell me how to decided which ones are good or is is better to just mine some of each one and hope that one day they will be worth something.
