WTB Look Clipless Pedals - $

I just found some cycling shoes, and am now looking for some pedals so I can get rid of the toe clips.  The shoes are Shimano TR30s, and the product description says they are "SPD-SL / Look* SPD-R and SPD cleat compatible", and the seller has confirmed that he will be sending Look cleats with the shoes.  I really have no idea about pedals, and am working with a very small budget.  If anyone out there has some old pedals kicking around that might work for me, please PM me with the details.  Thank you so much!
