What's your favourite cheap LEDE/OpenWrt device?

Define "best".

Keep up-to-date list of widely available devices which satisfy:

  1. ALL of the properties below:
  • Available today in most parts of the world
  • Fully supported by OpenWRT (working both 2.4 and 5 GHz WiFi, working NICs, working swconfig)
  • Stable software for everyday use - can work for at least several months without restart
  • More than 4/32
  • Well defined support per hardware versions if there are more than one on the market
  1. As many as possible of the properties below:
  • Easy initial flashing (software only). Mention other available options for those who are familiar with screwdriver/soldering/serial ports etc
  • Relatively cheap - compared to similar devices
  • Gigabit wired ports (although this is a dealbraker for me, some people might not require them)
  • Working USB ports
  • Working hardware offload
  • Low power consumption

Such an example is good old Archer C7 v2, but it's getting a bit old.
