It is short and memorable, but a quick search does not show a very large pool of obvious buyers, but you never know with this type in .COM.
It is one of those brand types that could sell for a lot or never get an offer.
As a re-seller not that much, but if you own many of this type of domain you will make some end user sales. It just does not work as well on a 1 domain basis.
Looks like an abstract of "R Kelly", mixing it up. If you fetched any serious bid at the level you mentioned, I'd absolutely take it. I wouldn't really consider this to be a XX,XXX domain, under most circumstances. IMO
