re price, the only limitation of the free demo version of Blitz3D is a more than adequate / generous code length limitation so is I think perfect tool to introduce to your students.
re "friendlier" alternatives, Blitz3D is not impaired by any hair brained click and play semantics where you will end up simply teaching the use of an app and not actual coding skills.
