Does $1,000 seem right for tax preparation?

This year I started my own corporation for my consulting business. Last year my CPA charged $250 to prepare my 2006 individual tax filings. This year he charged $1000, including my 2007 individual and corporate filings. That seems like a lot of money to me, but forming a corporation saved me thousands of dollars. My CPA did a great job, but I’d like to know if I’m getting a deal or getting ripped off.
