Cant recommend Digital Rev. Their reviews have no substance, and there's little entertainment value as i find their humor crass.
1. For straight-up informative, concise, and relevant reviews: DigiDirectTV. And, the sample photos actually have artistic qualities, to give the review merit. Unlike many other reviewis (Digital Rev especially)
2. The DigiDirectTV presenter covers more camera gear on his personal channel Blunty3000
3. Finally, TheCameraStoreTV is quite good. Less straight-to-the-point than DigiDirect but still an enjoyable watch.
Phillip Bloom is really comprehensive but he covers more video gear than still photo
