Depending on what you already have, a Paul Chain Keeper will only set you back $45 new.
My RF n-w chainring cost me $46 and an SLX clutch dérailleur cost me $50 when I set up my last 1x10.
you could also get an outer bash guard from BBG (104bcd) for $18 and an N-gear Jump Stop for $12 ($30 total).
I have bikes configured all three ways without issues.
