We do mostly baseball and in our first year, we used a bunch of retrosheet data for historical data and we went with BIS for current season data. They're pretty laid back and their data was pretty detailed for us. Recently, we went with MLB.com's xml data over at http://gd2.mlb.com/components/game/mlb/ where we had to do a bunch more calculations to get all the data we wanted, but it's free (for now).

We also looked at XML Team and I found their prices to be completely reasonable and they have a per document pricing structure which allows you to control your costs to a much greater extend.

We also spoke with Stats Inc and found them to be pretty unreasonable in terms of dealing with startups and for home projects.

Hit me up if you want any more data or if Benchcoach can help with the data on the baseball side. We're looking at expanding it to football and basketball this year so we've been speaking with XML team about that.
