A good specialized site and YouTube channel is Garage Gym Reviews [1]. Their reviews are clear and thorough and should be useful references for people buying gym equipment for the home.

The owner can go into obsessive detail about equipment features that I, at least, have never thought about, like knurling on barbells [2]. I have learned a lot from his videos.
