you'd be suprised how many home users look for professional products when they dont need them. in your case you will want the higher accuracy (even though sometimes it doesnt matter).
i agree, its hard to find good reviews at times. the best reviews are often the ones left by people who buy the products (such as on newegg, amazon, etcetera). you have to weed out the idiot responses but overall you get a general feel of the product.
thats about all i can say..
