Equal Estimated Tax Payments

[I Yam What I Yam]

Since we are on the topic of estimated tax payments, what is everyone's favorite tool to calculate you taxes when you have lumpy income? I could make a spreadsheet; however, if there is a usable tool out there I would probably just use that tool instead.

Perfect, thanks. I was doing a spreadsheet, too.
