Speaking of RID, as the deadline approached for compliance there weren't many options to choose from and most were not too far below the price of a used Spark. Holystone advertised one IIRC for around $70 or $80 and I got one for Christmas. Fast forward and I saw them for $30 on a Prime sale. The Spark is still quite a gadget, but the flurry of drones weighing in below the 250gr limit offer amazing performance. I wouldn't mind getting a newer one, but truth is I don't fly the one I've got much.
