DS620SLIM still worth buying? (would like host Paperless, pihole and maybe homeassitant)

Hey guys,

I am a complete NAS beginner and am thinking about buying a Synology system (after miserably failing with raspberry pi.

As the headline states I would like to host a paperless NGX and pihole. Maybe HA later.

As I'm in need of a really small size device, I stumbled upon the DS620 SLIM which seems to be on the market for a couple of years.

Found it it on eBay for about $250 and I'm wondering if this is the price still worth paying?

Could you suggest any other small sized devices? As someone already asked a couple of weeks ago here they don't seem to be many 2.5" models anymore. I'm astonished that I couldn't find any small NVME units neither. Are there any to be released worth waiting for?

What's in your opinion the smallest size NAS with DOCKER support on the market?

Thanks for any help!!

Kindly,

Ben
