It's a done deal. Just bought a Axim X50V off E Bay. Thanks for your input and time everyone!
This is exactly what I run. If you are going to run the NF / exbal program. I suggest you pick up a $10 SD card from staples. Unless your axim is coming with one. Then when you install the program choose save to "SD card" instead of "device". This way when your battery goes dead all your data will be safe.
