If you don't mind used, I can sell you one (or more).
Or, if you want new, ebay user Nicade has NOS 4-way Wicos up for sale. Buy one, disassemble it, and swap me the 4-way body for an 8-way body. You'll still have the brand new switches, grommet, and handle, and I'll be able to convert one of my excess 8-ways to a 4-way.
PM me if you're interested.
