Hi Jayz from a fellow Warnervaler.
I use an iPad with Co-Pilot which cost about $20 (the software that is; the iPad much more). It has all the waypoints I have ever needed and, if it doesn't, you can easily create them. There are no moving maps, airfield details or anything but you get a nice line that tells you if you are on track or not and all waypoints show up on the screen as you pass them by so diversions can be easily achieved. I generally write out separate Warnervale Flight Plans so I have never actually printed out the flight plan itself but you might be able to do it. It doesn't give you radio details. Headings automatically correct once you put in the wind from forecast.
I didn't get this until after I completed my PPL (about 6 months ago) 'cos I thought it would be much better to be able to do it without the electrics and I knew Wayne would be ****ed if I was cheating. But on my first big trip as a PPL around half the country in PRF last October, it was a great comfort to me (and my wife) to be able to double check my course.
The software also works on iPhone so we actually had three GPS units in the plane - iPad, Wife's phone, my phone.
For the money, I think it works great and I can't see me buying a separate GPS unit.
YMMV.
