Hikey 960 Availability

I can not find any Hikey 960 anywhere for purchase.
Are they obsolete? What is the best replacement for Hikey 960? Is the Hikey 970 pin compatible with 960? Thanks in advance!

That depends on your needs and the features you want, basically every 96boards consumer edition is pin compatible (at least at hardware/electical level): Consumer Edition Documentation - 96Boards
