Ubiquity Bullet M xw - can't find unit for sale

I went in this order of a) searching for a replacement bullet device to replace my current single band Alpha Tube 2H b) searched the table of hardware and found the Ubiquity Bullet M xw supported as a bullet style router with dual bands. c) after spending a half day searching I don't find any products for sale online by Ubiquity that have a description exactly like this.

Can anyone assist? Thanks!
