Metal Resonators

Has anyone seen the Regal RU-100 or RU-200 metal ukes? As far as I can tell, they are the same except the 200 has F holes in the top. Are they they the same size as the Recording King RU-998?
Comparison in sound or quality?

Here is one of those Republic resonators. This one (worked on) doesn't sound too bad.

Reading the comments:
"Needed fretwork, better nut slots, better bridge saddle slots, etc.
It sounds and plays ok now, but it was a disaster when I got it."
