Apologia Chemistry and Biology: Molecular Models at Good Will

Update!  Good Will has a new listing for Molymod Molecular Model Sets. This is a terrific deal.

I am planning an Organic Chem model for Chemistry.  It helps to use molecular models to teach Organic Chem.  Good Will online frequently has listing for molecular models: Prentice Hall Molecular Organic Chemistry Model Set, Molecular visions Model Kit, Student Molecular Model Set, and Flexible Molecular Model Set—this type makes molecules which are hard to understand.   I like the Organic Chemistry Model set.  These have larger atoms and easier to assemble into organic molecules.  Here is a similar molecular model kit on eBay.  This kit is similar and priced at $12.  I bought this Lab-aids Molecules of Life Kit for my Biology class.  It was pricey; I do use the molecules for instruction in Biology, Chemistry, and Biochemistry.  The molecules are small; however there are enough atoms for a large class to build models.  I need to step away from the Good Will and eBay listings for molecules; there is a large box of the kits in my basement.
