I highly recommend a 30 Day trial subscription on Consumer Reports (CR) online if you're looking to buy a big ticket item. You can put in your CC# & other details and get free 30 day access to CR testing of a lot of products. Then cancel before the 30 days are up. You may end up paying a little more for a top notch product, but you can be assured if CR reviewed it, you're getting what you pay for.
Maybe there's a market for verified customer reviews of popular items - even ones that aren't big ticket. Consumer Reports might grow to cover additional items and perhaps develop a browser extension for subscribers who gain access to trusted reviews.
