Does a blog like this already exist?

I spend a lot of time in Google but I have not been able to find a blog or website that addresses the questions that I have about purchasing educational technology. I am not talking about opinions on whether technology has a place in the classroom. I'm talking about, given that we are offering digital video editing in the High School, which headphone will survive the year? (SchoolPhones: trust me, the headphones are constructed a lot better than their website).

If anyone knows of a site/blog that I missed, let me know. Meanwhile, I'll blog my experiences as a starting point...
