Query: The solutions guide by David Heyd is totally inadequate.

I am currently involved in a course which uses the Calculus text authored by Larson Hostetler and Edwards. I find the text to be clear and understandable, and also well laid out(with very few exceptions). The student solutions guide( or the solution guide for students if you prefer) which accompanies the text is a rip-off. The cover says study and solution guide, and apparently what this means is whatever easy problems they could get Mr. Heyd to work. The solutions manual is expensive and has approximately five problems worked per section. For those of you who need a solution guide for this text, I do not recommend this one: it is a huge waste of money, and a rip-off.
