josecanuc's Journal: Finding relevant and useful product reviews online?

A problem I've found is that when I want to purchase or otherwise invest myself into some product or service, I want to know what others think about it. Especially for those things that are offered be multiple sources. It's so hard to find reviews that are by techies and for techies; a google search of "[productName] reviews" yields link farms and the ever-so-useless CNet reviews and epinions sites.

I've got a Blackberry 7100i from Nextel and am in the market for a bluetooth headset for it. Has anyone out there got any recommendations or comparisons from actual use?
