What he says (below). The jet, reasonably tricked out, is more like 2.5X the price of an SR22, plus brutal operating costs and very difficult type certification. I just don't see the numbers there to have a major impact on SR22 used market.
G1- G3 SR22's remain a great value, especially G2's. For $200K or so, you can get an SR22 with a fresh parachute. For the price of a mediocre 182, you get a plane that has faster speeds, avionics that do just about everything (with great redundancy), great fuel economy, and...most important (for me anyway)...a parachute.
Insurance rates have come down a bit, due to Cirrus' remarkable recent safety record. (Cirrus got AOPA's safety award this year).
Also, keep in mind, not all those "positions" by SR22 owners will result in sales. Many are actually marketing their "place in line" now.
Unless you have money to burn, focus on earlier Cirrus models. And if you go for the jet, I live in So Cal and will happily share expenses during a flight any day, any time, 24 x 7!
