Ok -forgive me for going against the consensus of opnion on this one - but, hey we have all got different mindsets. (and I know I have expressed this opinion before)
I do think the(multi) domain developers mindset is often controlled be a narrow range of whats seen as 'good off-the-shelf development' opportunities, Coupon code type sites being one off them. Please don't get me wrong, I have a few "Coupon" type names myself.
So yes, the domain put up for appraisal could well be be put together and raise good commissions and indeed sell-on. But, I can't see it entering a end-user mindset as a primary choice domain doman name only purchase, And to be talking some of the valuations given thus far, (as a non-developed domain name ony) is a step too far imho
