Unfortunately I have to say less than reg fee for it, sorry.
Here you are ways leading to this appraisal:
1. Triple not-premium letters; currently there are still a number of Triple-Premium LLLL.net available for hand reg (not to count the Four-Premium LLLL.net still dropping and the current prices of Triple/Four Premiums LLLL.net in the resellers market)
2. Let's say that we want to apply the "10% rule": HUVZ.com was sold at Sedo for 100$ last December, so 100/10 =10$ = reg fee;
but you have to consider that LLLL.net are still far from being all sold out, so you have to lower that result (that leads, again to "less than 10$" = "less than reg. fee")
My humble and personal suggestion:
Try to develop it and then sell the website to have some positive income.
I've just made a small search trying to give a particular meaning to "HUVZ", but the closest stuff I found is "High-tech Unmanned Vehicles" "HUV", as referred to a korean videogame (the other option is the IATA code for the airport of Hudiksvall (Sweden) :o).
Obviously there might be more meaning of HUVZ that I don't know and that I wasn't able to find performing a fast search on the web: in that just case please feel free to post them.
