*DO* buy a plane.
But not any plane.
I did my instrument, commercial and CFI in my Super Viking.
No regrets.

You won't need 100 hours inspections, for as long as you don't rent it or lease it back (which may not be a bad idea)

There are risks, but if you buy the right plane (and get reasonably lucky), you'll get all your ratings and sell the plane for what you bought it for.

And don't worry about the G1000.
Most VFR new students fly better when the panel is covered with a sectional.
True story...

Tailwheel?
HELL YEAH!!!
Please PM if you need more info, I have bought, trained in, and sold several airplanes. Tailwheel, nosewheel, multi(s), gliders, everything...
