I currently hold a Private License and would like to continue onward with Instrument Rating. At this point, I'm not sure if I'm going to pursue aviation as a career or not. I may, or I may not.

I had initially started flying with the intention of becoming an airline pilot, but after completing my Private and talking to more people in the industry, I decided that the life of a commercial airline pilot may not be for me as it seems to take a toll on long-term relationships and family life.

For the time being though, I want to pursue my passion for flying and press on with the next rating. I might at some point decide to fly for a living for private outfits. I'm not sure, but I digress.

So, I'm comparing two schools. School A has airplanes that are equipped with KLN 94 GPS receivers and school B has an airplane that is fully glass with a Garmin G1000 system. On days the G1000 might not be available, the school also has an airplane equipped with a G430.

The other consideration is that school A does not rent aircraft, while school B does rent airplanes. In the future, if I want to rent an airplane from school B, I would have to rent one with either a G430 or a G1000.

A third school in the area rents G1000, G430 and KLN94 equipped airplanes should I decide to rent, but I'm not too thrilled about renting from that third school in the future.

My question is this: Is there an advantage to going with one over the other? Which is going to serve me better in the long term?

And what portion of IFR training involves GPS navigation?
