Exactly my opinion. Six is about right IMO, but even four would probably be sufficient.

I'm sure you already thought about it, but you can save some serious money by making a DIY C-switch. The material cost will be less than five bucks. If you're not confident in your soldering skills, perhaps you can ask a friend to do it for you? Anyone with a little experience can make such a switch. You don't need a PCB, just solder the components directly to the lugs of the switch.
Let the thunder roll and the lightning flash, I'm doing alright for country trash.
