What's the best way to sell some redundant handhelds?

I have like 10 handhelds that I no longer really use and am looking to off load them None are really too old but I have a RG Nano, Funkey-S, Miyoo Mini Plus, Miyoo A30. Just ones that I don't think I'll really come back and play that often. Right now I'm fine with keeping my Odin 2, original Miyoo Mini, A28xx things like that. Is eBay the way to go or should I take another route?
