There's also one by William Levak, somewhere on FUNET.
If you're willing to wait some months, my 32k/512k RAM/ROM cartridge
might finally see the light of day. It is more than a RAM expansion.
It has a boot-up menu where you can go to BASIC (unexpanded, 3k, 24k
expanded) or select a program to be decompressed from the ROM to the RAM
and started. Both BASIC programs and cartridge-based programs are
supported. Unfortunately 512k won't hold even nearly all programs made
for the VIC-20, but that's the biggest Flash ROM that is available in
5-volt technology.
Since you're in Sweden, have you tried Elfa or the Ericsson component
distributor?
