Lifehacker:
Outsmart Brands does the research for you and shows more affordable versions of popular consumer products. The site shows you the best you can get on a budget. They just launched, and while they still have more items coming, they have a pretty decent selection of stuff to start with. You can’t yet search for specific items, but you can browse their categories and get a pretty good idea of what to find.
I have been lusting after a decent stand mixer for a while and Outsmart recommended one that cost more than $100 less than the comparable KitchenAid one. If you’re on a budget and looking for inexpensive alternatives, check the site out.
