One of the best dutch webshops, coolblue.nl, actually has people responsible for each market section, they test the products themselves and have recommendations for the items in each category they think are the best. It's supplemented with user reviews, but still, it's nice to get a semi-objective indication for which products to look at. The pride themselves in customer service, only sell a select range of products for each category and you can tell real time and effort went into it, this, in turn makes this shop pretty trusted by people. That's both good and bad, because now companies could approach them to get into their favours, but still, from what I've been able to tell, they actually offer some good recommendations.
