[SFDXA] Voice Keyer

[Sebastian, W4AS]

I recently sold my old rig that had a built in voice keyer.  For my new rig, instead of getting the internal one, I'm thinking I should purchase an external one.

I'm looking at the MFJ-434B.  I like the fact that I can make up a simple external switch box, instead of having to push the bottoms on the box; or on the rig.  

Anyone here using, or know of, a different external voice keyer?  

Before anyone suggests software such as N1MM - I do use it; but I still want a voice keyer when I'm not in a contest.
