Allow me to add a thought on 2 seat vs 4 seat:
If your goal is to fly 200 hours as a stepping-stone to a CPL and you want to keep the costs down, then go for a 2 seater because it doesn't matter too much whether you get your PPL in 45 hours or 65 hours. However, if your goal is to get a PPL in minimum hours, you will do that in a 4 seater. By that I mean you absolutely WILL get your PPL in 45 hours (or whatever your NAA requires). Why? Backseating. There are 4 ways to learn to fly a plane: Front seating, Back seating, Simulators and Chair flying. If you learn in a 2 seater you get 45 hours to get it right. If you learn in a 4 seater with a like-minded training partner then you get to do everything twice, once doing and once watching. Believe me you will learn just as much from the back seat for free.
Add in some chair flying (literally sitting on a chair and imagining you're flying, running through procedures and checklists etc) and with consistent flying you can guarantee a 45 hour PPL. Anyone who says it will probably take longer didn't do all those things.
