To be fair I think all devices should be listed and line itemed out in an excel worksheet or google doc (kinda like consumer reports) as the number of manufacturer's and devices is quite extensive and probably should include some gear no longer made as place holders/base lines or for reference purposes
I would include everything I could think of (Aaton Cantar down to chinese garbage such as the Alesis palmtrack) - below order is simply to give an idea
Aaton Cantar
Nagra VI 60th Anniversary Edition
Sonosax SX62R
Aeta 4Minx
Sonosax SX-R4
