All other things aside: I would buy two switches.
Why: redundancy.
Just in case there is the proverbial "puff of smoke" and the switch is dead.
You still have (hopefully) the other switch to at least keep some network devices online.
Or be able to swap switches for troubleshooting purposes.
Redundancy, etc. or may not be a viable consideration - and you still could have and use a direct connection or two via modem or router.
Always good, I think, to have some built-in options.
Just my thoughts on the matter.
