zerotier bridge device recommendations

[Daniel Denson]

I'm looking at the NanoPi R1S, R1, or Orange Pi R1 as a simple bridge device for Zerotier.  They all seem to have some limitations that likely mean ~100Mbps either from the 100M ports or the R1S' USB2 connected port so that's fine. 

 

I'm most drawn to the R1S for price and included case.

 

Questions are: 

1) Are these the only decent <=$30 devices for this task?

2) Is one of these known to be more stable/reliable?

3) Is there a likely software support issue with any of them?

 

The deployment model is pretty simple.  Plug WAN in to and DHCP port, have the firewall locked down tight, and bridge a ZT network into the LAN port.
