Foreflight is nice and worth the money but if you dont have the iPad ect to start with then it can be expensive to switch from paper to touch screen. I have the iFly 720 that i use now, its a moving map touch screen that requires no external GPS antenna, such as the (bad elf). I still keep a tac/sectional everywhere i go, and it has come in handy a few times(plus more fun). I learned to fly with paper charts and the ol compass and e6b and you really feel invested in your calcs because they have to be right on or your screwed.
