[edit reason] Please, no specific domain names. [/edit]
But weighing against that is having the opportunity to use a shorter domain name than an 'original' would probably be, and one word rather than the two you'd need in most niches these days. Plus if it really is 'clever', then it will stick in people's minds.
I have a couple of such domains, but neither were a first choice; always worth a couple of hours checking what good solid .coms are still untouched ... you'd be surprised.
And I got one of my 4-character 'clever' names on ebay for $20.00 - including shipping ;)
Two weeks later, I failed to win a nice five-letter domain (bidding topped $25.00), but the auction got my mind working, and I got a correct alternative spelling (brand new) instead.
This isn't just self-ego-boosting (OK, mostly), my message is to look at ALL the options; there's never just one right answer.
