I prefer the CD version of TurboTax over the downloaded version. I don't use the online only versions because I want to be able to open previous tax returns with the version they were created with, just in case that were ever necessary.
For what it's worth, I bought the current retail version of TurboTax Premier from Amazon for less than $70 including shipping. You can use it to prepare unlimited returns and it includes 5 free federal return electronic filings.
