If I remember right, I still have couple switchless kickstart switchers in my shelves.

Supports 8 kickstarts so you can easily fit 1.2, 1.3, 2.04, 3.1 and DiagRom in the same device.
I've usually asked 27e (Paypal friends&family) for it in "Commodore Amiga"-facebook group which includes shipping to Europe.
