Good places to buy quality used/refurbished joysticks?

Looking for a couple of VKBs Gladiator NXT EVOs for space sim gameplay.

(Feels like my Thrust-master T.16000s are pretty outdated at this point.)

Wondering if anyone has tips on buying those more affordably.

I’m guessing I’ll just need to save up for them and cough up the money. But wondered if anyone out there knows a better way.

Thanks!
