I've used Turbo Tax for about 10 years.
Each year you buy the new software for the year. No yearly upgrades. It was $34 less $10 rebate from Costco for 2003 tax year. Fed/State (DEluxe version) Usually goes on sale just after Thanksgiving.
Satisfied. But last year was a real hassle. I use several computers and laptops and don't like to be restricted to which PC I use. My wife can do her thing on another computer too. Also, PCs are being replaced or modified, so you need to be able to move your software around easily.
If you can get your taxes done for $80 - that's a bargain. I'm assuming they do a good job. Your taxes sound pretty straightforward, so maybe that's why they only charge you $80.
For me, the software is nice because I don't have to worry about calulation mistakes. And the figures are transferred from form to form automatically.
If you wait till around Jan 15th, basic (FED only) Turbotax can be found for about $20.
