David Carr of The New York Times profiles Brian Lam and his tech recommendation site The Wirecutter:

Using expert opinions, aggregated reviews and personal research, they recommend a single product in each category. There are no complicated rankings or deep analytics on the entire category. If you want new earphones or a robot vacuum, The Wirecutter will recommend The One and leave it at that.

The site is great.  I always consult it before making a significant purchase.
