I have a partnership agreement I'd like a second opinion on, but I can't afford a lawyer right now. What other resources are out there? I've found a web-based contract review site that uses attorneys "from the 10% of U.S. law schools"- Contract Gurus. They seem legitimate (twitter and blog response is positive), and they're definitely affordable, but I don't know.
Any one have any experience with them or a similar service?
You shouldn't be signing a partnership agreement without legal advice. If you can not afford to hire an attorney do not sign it. Look up the legal liabilities of a partnership agreement, and then you can see why it needs to be reviewed by an attorney.

You don't say where you live, but here are a few generic places you might look:
