In my opinion, ASICs are worth the investment if your looking to make a profit long term, There are a few reasons for this but I will just list a couple 
1. At the current rate of ASIC Manufactures actually getting a product into the consumers hand if you are only just placing an order be prepared to wait a long time to receive your unit.
2. Only those that receive ASIC's from the first batch's released will quickly recoup there investment because the difficulty will increase and the evolution from utilizing Graphics cards for mining switches to ASIC's as it did before from CPU to Graphics cards. So ASIC's will become the "Norm" for mining.
Now you may want to ask yourself this... based on the current increasing value of bitcoin, would you make more of a profit buying bitcoin now and selling once the price of bitcoin rises? or spending your money on purchasing an ASIC which you may not receive for sometime?
