I just want to point out a couple of websites where you can obtain free past performances. I use both of these and print out the pp's at home. This will save you some $$ - the cost of printer ink and paper is far less than buying a program all the time.
Horse-races. net is one of the best horse racing websites. They have a free past performance link. You can get free pp's for certain trainers who have horses running. Some of these include Todd Pletcher, Bob Baffert, Gary Contessa, Barclay Tagg, Doug O'Neill, Linda Rice, Kiaran McLaughlin. You can quite often get the whole Saratoga card for free!

For Canadian racing fans, check out the Woodbine/Mohawk website for free programs for Canadian racetracks. Check it out at: http://www.horseplayerinteractive.com/Racing/Schedules.aspx
