You might also want to look into MagicRam flash cards
(http://www.magicram.com). I recently purchased their 4mb card, part
number AJT-004MAS, and have no problems so far using it in my Ogo100.
Price was great too at about US$179 for 4mb, much less than a SRAM card.
Additionally, with flash ram cards there is no battery to worry about. To
be fair there is a supposedly higher drain on the Ogo's batteries than
using a SRAM card. I have noticed no difference in battery life, it seems
as short as always :-)
