I'll throw my lot in for Hero Lab too if you're willing to spend money. Obviously it doesn't beat free if that's your budget, but if you can spend some money, there's nothing better out there for Pathfinder imho. I really don't think it's that expensive when you consider that all the Pathfinder add-ons are one time purchases, versus having to pay an annual subscription.
For example, the core product is $29.95, and that includes support for one game system, presumably Pathfinder. That includes the core Pathfinder book, everything in the Inner Sea guide, and full support for Pathfinder Society. Now if you want to add content from the Advanced Players Guide, Advanced Race Guide, Ultimate Equipment, and Ultimate Magic, that'll run you about $10 per, or a total of about $70. That's just under the price of Wizards' cheapest annual subscription price to DDI, except that you only pay it once with HL. For me, that's pretty good value.
Oh, disclaimer: I don't work for the Hero Labs guys, just a fanboi.
