IMHO buying ASICs now is much akin to pissing in the wind.
If you want to invest in hardware, I suggest GPU equipment for mining Scrypt.
My $.02.

What do you base that off of?
Do not buy gpus for mining. Go look at the prices and earnings of coins today, then look at last month, month before, month before, you get it.
Look at how much was made on dogecoin pump originally, look at how much is made on whatever bullshit coin came out today for a pump a dump.
Don't believe me that it went to shit, go look at the prices of gpus. They were being scalped like crazy, now the major distributors are selling them for their standard prices, probably because people realize gpus are becoming non profitable for new rigs and are they are not moving at the higher prices.
You can literary buy 3 antminers and psus for the same price of a 2-3000 khs rig. What makes more a day? The antminers would make 4x as much.
Will the antminers earnings potential fade away quicker, probably. Will the resale be low compared to gpus, yep.
Hopefully gpu mining will recover, or these n-factor jane things will catch on, but at this moment it is not worth it.
If buying an asics rig is pissing in the wind, buying a gpu scrypt rig today is like having explosive diarrhea into the wind.
