domain DOMANSION.COM & others

[gartrout]

One of a few domains I have with the thought of promoting domain names.
What do you think? Which is the best?

DOMANSION.COM
NAMEBURG.COM
NAMESHOUT.COM (my current site)
SPARENAMES.COM
MAGNUMNAMES.COM (& MAGNUMNAME.COM)
CC-TLD.COM (& CC-TLDS.COM....for a narrow focus)
MOSTVALUABLENAMES.COM (& MOSTVALUABLENAME.COM)

Thanks for your input!
