I'd agree that both are somewhat overpriced.. but there is some value to being able to buy and sail as opposed to buy, work/fix, then sail. And, more importantly perhaps, keep in mind that these are asking prices and what they'll actually sell for may be somewhat less.
A serious offer from a qualified buyer could change those numbers.
On the face of it I'd try for the Mirage first, but for our area the Hunter may well be fine is she's passed a critical survey.
