Unless you have enough in savings for your family to live on for 6 months, and ON TOP OF THAT, whatever you intend to spend on this bike then you have no business shopping for a new bike.
I got this for $7.50 + tax. I had to put one tire on it - $10 at Performance. This is the price range you should be shopping in unless you meet the criterion above.
