I'd love to hear how others manage their homeschooling budget when using what I refer to as "organized" curriculum.  I know there is a wealth of free and inexpensive stuff available for download on the Internet, but I am not a person who can "make it happen" that way.  I need a true curriculum to walk me through and make sure I'm covering all my bases academically.  I just don't do well looking here and there to piece it together.  However it's no small thing for me to just drop $100 here and there on the latest and greatest, trying to teach 3 boys!   I'm a master at finding deals on eBay, but what are some specific curriculums any of you have found to be budget-friendly?  We do best with unit studies (I have Konos but it is VERY time-consuming for the parent in prep work!!).
