Free vector drawing program?

I thought maybe some artists could give me some suggestions.  My dad wants me to design a logo, but since it's not my profession, Illustrator wouldn't be worth buying.  I have it done in Photoshop, but I'd like to make a scalable vectorized version.

Thanks /comp/

Sorry :<  I would take the life of my own thread out of shame, but I don't know of a delete button on the text boards.

But thanks, those links really helped.
