I bought this keyboard for around $55 a year and a half ago on Amazon, so this might be a decent deal. Definitely go for the blue switches. The brown ones are not good for typing as they activate too soon IMO.
They keyboard itself is solidly built and still works great. Although the keyboard is metal, the silver on top is painted. Mine has the black primer/undercoat starting to show through around the arrow keys.
I'd buy another, but only with a number pad and blue switches.
