Dick, you could upgrade to the 109SP. You'll get Chelton displays, 4-axis autopilot and a slightly longer cabin (more legroom) than your 109E, but still the same speed that you like. Plus a greatly simplified electrical system! There is a demonstrator available in Australia too. At least, there was last year when it did a tour round Oz and NZ.
Less training involved for you and you already know what to look out for with the 109 Series.
I take it the Genesys mod isn't looking too good?
If only Garmin would have an IFR certified alternative that could be installed, but they refuse to certify the 500 series to IFR and the 1000 is restricted to who can install it.
