Oh, if you're going to buy a GPS, you might consider the SkyDemon as well.
Tim Dawson wrote SkyDemon, a VFR flight planning program to run on your PC and during development got a lot of feedback here on PPRuNe. It's definitely not a bad product. It includes a PDA based program, so you prepare the route on your PC, then upload it to the PDA to fly it. Together with the latest NOTAMs, METARs, TAFs and whatnot.
From a few posts he made it was clear that he somehow hooked up with a manufacturer to create a dedicated GPS device for use with SkyDemon. And I just noticed it's available for pre-order now.
Welcome to SkyDemon, VFR Flight Planning Software and GPS Navigation Devices
If his past performance is anything to go by, this product might just blow the competition for VFR GPSs away.
