I did all my training in Robins - nice aircraft with sticks and really good visibility.
You won't be compromising much by going for the cheapest option there - in fact, I'd say you'd find the Robin a more engaging and enjoyable experience than the PA28's
Couldn't agree more! I also did my training on the Robin HR200 and wish I could fly one now, unfortunately my club has only Warriors and Cessna 172s. The Robin is much more fun to fly.
Regarding the number of hours to pass your PPL. I seem to remember that there's a formula which is connected to age. I can't remember the details but I know that it was pretty accurate. Someone may know it...........
