Though you have two words that can be monetized it is still a typo domain as I see it so next to reg-fee.
The reason you should use the exact CORRECT spelling of a domain is because we do not have the luxury of building a brand like Google did and even they only changed the word to make it easier to spell and it was sufficiently obscure beforehand not to be an issue, if people are buying domains then they will want perfect spelling, as mistakes even if intentional on your part will be harder to get into the public consciousness...even though people on the internet for the most part cannot spell anyway.
