Thanks for all that input. That's exactly what I was looking for — good comparison with not vested interest in selling anything....
I played Grab's Regal a little and liked it a lot, tho' I remember it as much heavier than the Nationals, Dobros and Johnson's I've played more recently. I think what I really need to do is trek over to Elderly and spend a day comparing.
I went to the music store today to play that Johnson again and was very, very close to buying. Glad now I didn't.
