There's Delphi Starter Edition, which is free for freeware / personal use projects, and 'free' for commercial apps until you've earned $1000 in total revenue. (At which point, they want you to buy a ~$2000 license. Hmm.)
It's the same with commercial CommonLisps, I'd love to use one, but the pricing is ridiculous for small companies / hobby programmers. That doesn't add up, you'd have to be 100% sure that you'll earn more than X dollars with your application and you can never be sure of that.
