I am about to buy one, I am just weighing my options as to which one is the best value, speed, weight, and size for the money.  I plan on using a Compact Flash GPS module in one of the PCMCIA slots and woala, a moving map over real-deal Jep charts....for pretty cheap compared to what it used to be.  You can buy a one time VFR/IFR chart deal in a particular area for around 129.00 I believe.
