Blue switches are the best for typing but the are also quite LOUD.
I would recommend BROWN switches. I recommend one of the Corsair or Cooler Master models based on personal usage.
If you don't require the keypad, I really like the following keyboard which I found for $100 USD (brown key version):

The Logitech G710+ is also a very nice keyboard but it's a lot larger. It also has rubber bumpers which the keys hit and it cuts down on the noise. It can be found at AMAZON fairly cheaply though watch who you buy it through.
