Also, if the current shiny new edition is 10th... look for the 9th. I seriously doubt amazing new breakthroughs have been made in maths, but the fact that the 9th edition is now "outdated" will depress its pricetag, new or used.
I'd recommend buying used, but look through to make sure the previous owner(s) didn't have some arcane highlighting scheme.
