Twins vs. Singles - comparisons

With the current depressed market for twins, it is interesting to
compare something like an SR22 or C210 to a Cessna 310. You can afford
a lot of gas, insurance, and reserve for overhauls; with a $100K+
savings on the initial purchase price. Also, I'd be surprised if there
is much more depreciation on the 310 or the 210 (aside from time on the
engines & props), while the SR22 will probably depreciate another $100K
in the next few years. Has anyone gone through the purchase decision of
comparing twins to singles recently? If so I'd be interested to hear
how the decision went. I included 3 current planes listed on
Controller.com as examples (disclaimer: I got the performance stats off
of various online sources so I'm sure that there are inaccuracies)

The SR22 is a really nice plane, but that 310 sure looks tempting for
the price. I'm sure the numbers look similar when an F33 Bonanza and a
B55 Baron are thrown into the mix also.
