Hi, John. The home centers have book sections that are full of books and magazines with various plans. There are also booksellers both on the web and real, live stores. One other source is on the web and a good place to start is www.zyworld.com/TheWick/ Wick's Weekend Warrior site has many links to plans. You can also do a search on any of the many search engines.
Finding plans is no problem. Finding the right plans for your wishes and skill level might take a little longer but they certainly are available.
