Or just borrow the newer edition for a night ...

... and cross-reference the problems to the older edition. Good profs may even do this for the class.

I've found that the publishers usually just slightly re-arrange the problems (and the chapters), apparently for the sole purpose of killing the used book market.

I'd rather be a hungry patriot than a satisfied slave.
