Alternative To Quickbooks?

I need a program that will simply track book sales for 2 of my books. I basically just have to track sales and state sales tax. I’m guessing that Quickbooks would help me track all this better than my massive spreadsheet will, but the reviews say it has so many problems…
I should note that I am NOT going to be hooking it up to a bank account or anything fancy; I am basically using it as a tracker and as a utility that can create reports and track sales for me (and who has paid!!!)
Please I really need some advice in this arena!!
PS. I have a new PC with Vista on it.
