what is the best ethernet bridge to get?

[me2@nowhere.org (Bart)]

Ok gang I got it!  I now have an IIsi Mac as a server hooked to my //e and my 
GS.  Works great too!  but I still don't have a modem (except the 1200 baud 
one on the GS ;)  on the apple side.  SO I d/l with my PC network, then unplug 
a SCSI from the MAC, reboot the PC with it plugged to it, then run Transmac to 
transfer, reboot and...well you get the picture...
So I wanna Ethernet/Appletalk bridge.  What should I get? My  PC net is an old 
10b2 type.....
