@vandereydt: PPL on a SR20 will give you a lot of training on the not-so-good SR20. If you managed the underpowered 20, the 22 will be much nicer. I don't think you need the 22T though, as the advantage is not that big and only for high altitudes. Only if you are cruising frequent FL200 the expensive and maintenance hungry turbo will be of benefit. Going below 200h a year I would opt for the non-turbo. To the G1000 - I guess about 100h a year keeps your basic knowledge up to date, so at 150-200 I wouldn't see a danger in such glascockpit.
(Regarding: I have also looked at refurbished aircraft. Piper Matrix ... Meridian Bononza, Cessna Twins 320 - 340 - ... -> I suggest to clarify the typical mission profiles! These machines have quite different advantages for different use, so before spending much bucks for a machine you find out unsuitable, do yourself a favor and define what you want to do.)
