definately skip the glass cockpit thing. Get your training in the absolute CHEAPEST airplane you can possibly find and save the money, you will definately need it. If you so desire after your ratings have someone with a G1000 sim or avidyne sim just show you a few things at the most and you really dont even need that.
The plane I fly is all glass and id say over 80% of my class had no glass experience and up to now none of them had a problem with the transition. The whole "glass" training thing is a myth. It does not take you 200 hours in glass during training to be able to handle the transition. Id equate it to to jumping from a 152 to a 172 and no more difficult than that.
