Dear Kat,
1st - I fully support Chris that one could and should build his own
device and one will benefit a lot just from this step.
2nd - if you really want to buy 'stuff' I may suggest a system that
consists of an accelerometer (I used PCB) with power module attached
to a Compact flash card from NI that is inserted in the Pocket PC
(i.e. Axim - 51 Dell). This system worked fine for me.
