stay where you are
I have experience on P2002 a C152 - even I admit a limited experience. I see no reason why you would switch school to get a chance to pay more. P2002 has better performance than 152 and unless you are pretty high (head room) you would be really comfortable in Tecnam. The biggest issue and difference is braking - brakes for Tecnam are operated by a level between seats, not by pedals. So it will take some to establish "hand operating system". Stay with Tecnam and enjoy flying a new airplane with a chance to look around - not to hind underneath the wing.
