I bought a 150G as soon as I passed my skills test. I have had it for 4 years now and it flies beautifully. Watch out for the early models with the Delco pull start though, the clutch on mine disintegrated leading to an engine rebuild at 2300 hrs (well over TBO). I would recommend a lightweight replacement starter and spin off oil filter as an immediate upgrade.
Fun to fly and cheap to run. Not fast but with a new prop and engine I get a steady 85kt at 2400 RPM. Full power will realise a max level flight at 102kt.
Short field landing is great, but beware of the take off performance, especially on soft grass you may not get out again without a strong favourable wind.
