Passed the checkride, now I need a good GPS, and passenger headset

YIPPEE! I'm now a private pilot!

I took and passed, the private pilot checkride on Tuesday.
What a relief! It wasn't nearly as bad as I thought I'd
be, and went very well.

Now I need an aviation GPS and 'Guest Headset', and I'm
hoping that readers of this list will have recommendations
about what to get, and where to buy it. Yes, I've seen
the eBay auctions, and I'm thinking of a higher end GPS,
maybe even color.

Any suggestions or experiences with specific models and
vendors will greatly help!
