I have the TW-1 and TW-2. As a backup, I have an old NiViking unit which 
won't speak SWR but will give a tone that goes higher and lower as you tune. 
That's a hard to find thing and I happened to fall in to it as part of an 
estate. Not letting any of it go, occasionally see the TW-1 and TW-2 for 
sale here and there used, have never seen the Ni Viking unit. I'm not sure 
someone technically minded would have a hard time building something like 
that Ni Viking unit.
