I caught a similar bug about a year or so ago, I bought a replica instead https://retrogames.biz/products/thec64/ and it satisfied my retro computing interest even though it wasn't original hardware.

If you do go down this path, note that retrogames has 2 similar products, the c64 (mini) and the c64 (maxi), the maxi is probably the best one to go with since it has a working keyboard.
