If you're in Germany, get 101 047 from www.pollin.de. That's a NOS 
GM71256-12 (41256), sells for 40 Cents and will work in a C64 if you 
connect Pin 1 to Pin 16. There is no reason why it shouldn't work in a 
C128 or any other system that uses 4164, as long as the DRAM controller 
supplies an 8Bit refresh (VIC and TED do).
