OK, I'll bite and jump in - get yourselves a cheap (Garmin 96 or somesuch) GPS. If you can afford (eBay ?), then a 296.
Why? Simple - you are at the beginning of your flying career and GPS will play a much larger role in this in the future than it does now (in the US this is already the case, Europe, as usual, lags a couple of decades and the UK a few more). It certainly cannot be a bad idea to acquaint yourself with the functionalities of what is already the de-facto standard navigation instrument.
That said, I am NOT advocating throwing the paper charts out the window. Use both, learn both and all the other navigation instruments you have in the cockpit.
Congrats to your new license and happy flying
