Where Have All The Two Seat GA Trainers Gone?

[Acrosport II]

GA is just way too expensive nowadays.

I am not sure what it is like in other parts of Australia, but I am really surprised around the airfields here in SEQ I am close to. The lack of two seat GA training aircraft.
I learnt on the Piper PA38 Tomahawk. A simple, solid built, Two seat, 112HP powered low winged trainer. Roomy Cabin (especially compared to the main oppositions cramped C152 Cockpit). A fantastic Aero Club or Flying School Trainer. Yet how many GA two seat trainers are active for pilot training now.

It seems if you want to learn on a GA aircraft, (well, near my local airfields anyway) you use a four seat 160HP C172 @ $370.00 an hour ++. There may be some LSA registered as VH, but generally 'Where have all the basic two seat trainers gone'?.

I can only assume no one is buying them because there is not a demand for them. Why?,... is it because GA is just too expensive to learn and fly regularly. Hourly rates, and $700 or more for a medical (not including any specialists visits).

Even a quick Google showed many USA training outfits using C172 or PA28 aircraft rather than two seater versions.

It's a shame they have stopped making such aircraft. Piper are still producing aircraft, but no 2 seaters.
Other main two seat trainers I can recall were Cessna 152, Beechcraft Skipper, Victa Airtourer, Grumman AA-1.
What would they use now. Some of the new alternatives seem fancy 'Plastic Fantastic's', costing over half a million dollars?. Would they still be flying in 30 - 40 years.

There are a few Diamond DA20 or DA40. They look more like a LSA Motor glider.

I'd like to see GA prosper. But maybe it's just out priced itself!
