Do you feel comfortable asking for a couple hundred dollars from some total strangers?

Factoring that number might become important to me for, say, $2000 US. How's that sound? Then I could buy a couple of nice quadcores to factor it for you.

This is at least the 6^{th } such thread: recent/unregistered, asking to factor a >120 digit number, and 'knowing' it is composite.
