WTB: Ethernet card for Power Mac 4400

I recently got a power mac 4400 from a friend as payment for fixing her computer. I've fixed the hard drive on it, and now I've realized that whoever had this machine before her switched out the ethernet card (it's a 200 mhz model). This machine will be totally useless to me unless I can grab a NIC card for it. I'd be willing to swap you the modem card if you wanted it, or I can pay for it as well. reply if you can help me out. thank you!
