Some die-hard traditionalists will always say start with steam gauges. To a career-oriented student, I would say train on the gauges. Many commercial airplanes still use them, and it's easier for a steam-gauge pilot to transition to glass than vice-versa. Plus you save money.

But since you are a recreational pilot, and may not have the time and/or money to achieve (and maintain) proficiency in both steam gauge and TAA aircraft, you need to ask yourself one simple question...

What type of airplane do I expect to fly? If you're going to be renting old beaters, better train on gauges and get real comfortable doing partial panel in IMC.

If you're going to buy a Cirrus or other TAA, or rent one, then the safest thing for you to do would be to get as much time as possible on the glass system you will be using, or a very similar system. Then if you ever need to fly a steam-gauge airplane, stay VFR.

Steam and glass are different skills...don't think one will transfer safely to the other without some training and practice. Insurance will usually ensure that TAA pilots get the right training, but there is no such mandate for a glass pilot going to steam. I'm sure this will be corrected by regulation or insurance once some blood has been shed.
