I wouldn't advise Asic. IMO it's the worst investment possible for miners. It's almost impossible to make ROI if you pay for electricity, because of the sharp increase of difficulty (mostly due of newer / more efficient ASIC being released every few months or so).
Only way to make ROI is to hold your coins and bet on a big price increase. But instead of buying the asic you might purchase the coins directly which will spare you the trouble and yield higher profitability.
Yet if you want to mine, GPU mining is much more profitable and more fun (or laborious it depends your notion of "fun"
).
