I also added popper so when you hit the switch it lifts the hatch over the latch and you can open it with one hand. I picked it up a my local custom shop for about $25.
I believe the Magic Touch kits run about $400 per door and that doesn't include installation.
Where are you going to run your gas filler tube??
