Reg. fee or less for all. I don't think gaumi is especially good either for the following reasons:
1. I doesn't sound especially nice to say. It doesn't have that wow factor about it.
2. It's not particularly eye catching or memorable.
3. There are lots of alternate spellings for the same sound. Gaumy, gowmy, gormy, gowmi, gormi, goumi, goumy... etc. How many would get the correct spelling if said on the phone? Probably very few.
Hope this helps. My advice - grace delete them all at Dynadot, get your reg. fees back and invest in some more worthwhile names.
