Lumia 1020

Only if its cheap. And only for the still photo shots and zooming capabilities. For everything else the 1020 has been long-since outclassed.

WP8.1 is only going to go downhill from here and 10 enters some relatively annoying or dangerous territory.
 
Maybe I should gone with the question - is it worth buying second hand Lumia 1020 for 90 USD.
that's not a bad price if it's in good condition but I don't think the camera compensates for the rest of the phone and especially OS today. Only if you know you're getting a dead-end phone. If a 920/925/928 is significantly cheaper I'd consider that since it still has an excellent camera, just without the raw MP count.
