[sdiy] Small Panel Mount 4 Pos Switch?

[MTG]

I'm looking for a small rotary switch that can be panel mounted. I don't 
really care if solder lug or PCB, not sure I will spin a PCB for it 
since it's being crammed into a (somewhat) vintage drum machine. It can 
be one of those switches that you can adjust the number of positions. 
SP4T is fine.

I see a couple of close candidates at Mouser here in the US, but I seem 
to recall Grayhill at least being really expensive. Here is one for less 
than a buck. Or is it just the mounting washer LOL?

Alps is also at Mouser. I guess I will need to source knobs now too.
