I use TurboTax and have been happy with it. I get the notion that getting a big refund is like giving the govt an interest free loan for the year, however my wife and I have used our refund last year to replace all the upstairs windows in our home and have a huge basement waterproofing/wall reinforcement project going on right now that will be pretty much paid off with our refund.
I look at it as a savings account that I truly cannot touch for a year. Getting about the same return rate :p
