http://mining.thegenesisblock.com/  is a good site to use.

Just select the actual unit you will be using and remember also electricity costs etc

ROI is subject to your beliefs. So I won't comment.

However I would suggest you check out he group buy threads

Canary has these for 10.5 btc, ROI is easier if you pay the best price

no ROI. even if you have free electricity, shipping and you already own PSU and your pool fee is 0% (and please note, that we are waiting for almost 1M avalon chips, KNC/Bitfury delivery and new companies still appearing)

this is clearly reflecting ASIC reality. so sad.(

Yeah its sad reading definitely.  However its a prediction.  The percentage increase may not be so severe, but I have a feeling that it may be more to be honest.  Adding to your own hashing power just adds to the problem
