Me too, especially when the presentation of the contract indicates that the other party desires information asymmetry (e.g. they look impatient and try to rush you, or they have a huge contract in a tiny scrolling window on their site). You have to be ready to walk away from the deal too, or why bother?
Still, I see some totally one-sided (and what I believe to be unenforceable) terms sometimes and I may sign anyway. For the other party to actually get what they want requires a lot more work than just getting my signature, and I'm firmly in the "Fucking sue me" camp.
