Agreed. I got a TP-Link TL-MR6400 for £70 on Amazon (B016ZWXYXG).
Seems reliable. I use it with a 24-month SIMO contract.
Much as I'd prefer a gigabit port and AC, I see this as a 12-month stopgap until 5G-and-band-43 hardware becomes available at a reasonable price.
Three unlimited SIMO, replacing 3 km ADSL line.
