Can anyone recommend a decent PTMP device?

Hello,
My longstanding OpenWRT nanostation M5 has finally died on me, storage has gone readonly and I don't seem to be able to switch it back. It's old, let's replace it.
Can anyone recommend a decent Point to Point/Multi-Point device, obviously with good compatibility with openWRT?

Or, recommendations on just a decent compatible AP or router with antenna connections I can make into a PTMP device with directional antennas?

Any thoughts and ideas very welcome.

Thanks,

Another Nanostation M5 device.

I appreciate you're trying to help, and a nanostation is on my shortlist, but I was after some alternative ideas so I could do some comparisons

Thanks though
