Support for EdgeRouter models aside from Lite?

After burning through several USB sticks, I replaced my USB stick with an 
SSD on USB, and my EdgeRouter Lite has been doing NAT, routing, DNS, DHCP, 
plus compiling continuously without any issues for more than three months.

I plan on getting a few more for some other networks. I'm curious if any 
of the other models are supported by NetBSD yet, such as the EdgeRouter X 
(cheaper, smaller, less memory but faster 880 MHz CPU) or EdgeRouter 4 
(more expensive, but 1 GHz CPU, 1 gig of memory, SFP, external USB 3).

Has anyone given these a try?

I don't know which scares me more - that people adhere to the idea of an
omnipotent being powerful enough to create the universe, but whose
supposedly most cherished creation is a race modeled after himself which
can't stop hurting and killing each other, or the idea that those same
people cannot or will not consider the possibility that the universe is
random and unfeeling, and it's up to us to create order and beauty out of
chaos and entropy.
