For resellers reg fee right I am afraid. For and end-user who knows. Have a look at http://3character.com/priceguide.html for latest updates and pricing.
I have FX1.us, and that seemed like good letters to me, Fx for Effects, and usually, special effects people like to combine numbers with their alphabets
I think it's way too early to think about resale value of LLN.us or any combination thereof. It might be worth looking into buying some heavy hitters for the future. Wait until LLL.us truly starts taking off, then i'd think about resale on LLN.us
