In last month there was 3 on allegro: 1 with unfinished sim mod (I bought it), with broken lcd and one fully functional with sim mod. Additional there are few Photons on ebay.

There is also almost usable Sailfish port for Photon Q so I think for now it's the only recommendable device with hw keyboard and some kind of linux system. I know it's not that polished like n900 but still I am wondering why there is almost zero interest in this device here: in center of linux/hw keyboards followers.

There is also ancient HTC Desire Z but with only 512MB RAM.
