No problem, get:
1 Fujitsu P1610
1 Power supply (Lindt)
1 Ram mount (Yoke mount)
1 Bluetooth GPS (OBS battery life)
1 Jeppesen Navsuite subscription for whatever area you need
Voila

Only drawback is that VFR charts are European, not US type for Europe (ie poorer)
Of course you can also have a look here if you want to spend more $:

Alternatively if you don't need enroute (moving) maps, you might as well pick up the an iRex eBook and download the PDF versions of the fields you need. Cheaper, but not quite as neat.
