DOnut,
I bought this last year, after we'd already completed one quarter of anatomy that included the musculature. So, I don't know how handy it would have been for that.
However, during thoracic and abdominal stuff...it was priceless and I loved it! I think I paid 60-70 bucks (with shipping) or somewhere around there.
We are talking about the ADAM Interactive atlas, right? Also, be sure that you aren't ordeing the 'teacher' edition...order the Student edition. From what I could tell, they are identical, but the teacher edition costs much more because of copyright stuff.
Also, this CD is NOT burnable. At least, I couldn't get it to burn. I know there are techies out there who could probably get around it, though.
