Going through my favorites gave me the idea that I should share some of the gold mine sites that I've stumbled across in my travels. Maybe save you a trip or two down the internet maze....
http://www.manualsonline.com/ I have used this to find instructions for a yard sale food processor, side of the road elliptical, and my very old convection oven hand-me-down. Also used it to download (print to pdf) a digital copy of manuals I already have to my computer.
http://www.instructables.com/ How-to's for all kinds of things from crafts, to diy, to survival stuff!
http://www.budget101.com/ Nice all-in-one 'do it cheap' site.
http://www.homesteadcommunitypost.com/ All things homesteading for all levels. The videos in the store are worth the money. The information in the forums are priceless.
http://www.hillbillyhousewife.com/ More frugal 'running the house' information.
http://www.motherearthnews.com/ How to do anything green or greener. My favorites include links on this site for 5 minutes a day for homemade bread, homemade ketchup, etc.
***Ps, this is ditto for any magazine you enjoy- look online for almost all archived articles and save money!
http://www.bulkherbstore.com/ Cheap/good herbs and herbal primer/recipes.

http://www.urbanfarmonline.com/ Sustainable gardening ideas for your backyard
http://www.grit.com/ Basically like MotherEarthNews for gardening/farming
www.pinterest.com When you need ideas, instructions, or a 'wow' moment- WARNING- major addiction element! This site was in 'invitiation only' mode when I joined. If this is still the case, email me and I'll invite you...
