The TP-link C7 was a good candidate a few years ago.  OpenWRT support,
cheap, AC1750.  They did decide to lock out firmware replacement due
to their (quite rational) interpretation of a new FCC interpretation
of regulations.  I hope that that has blown over.

Dave Taht, Vint Cerf and a cast of thousands pointed out that made it
harder for the FCC instead of easier, and they quietly changed their
guidance. (I was Dave's editor on that one: see
http://huchra.bufferbloat.net/~d/fcc_saner_software_practices.pdf)

Some vendors have continued to block updates, citing the original
guidance, but that's just their justification for an attempt to force
hardware replacement rather than software update.
