I'm afraid that the website you mention seems to be still under construction. I guess it's best to look through the options available at the
re-seller's page. However here you go - all the currently available modification (afaik) from the manufacturer / distributor (please pay attention to the fact that the models from the distributor don't have audio output support as opposed to the versions ordered directly from the producer)
Basic models (C67SM Carta Series)
- C67SM Carta? / Amundsen - same as C67ML Carta but w/o lighting and touch screen
- C67SML Carta? / na? - same as C67ML Carta but w/o touch screen
Touch screen models (C67ML Carta Series)
- C67ML Carta / Vasco da Gama - 1024x758 212dpi screen
- C67ML Carta2 / na? - 1448x1072 300dpi Carta Plus screen (=Carta HD)
- C67ML Carta+ / na? - 1024x758 212 dpi screen with Snow Field technology support (their own approach to the EInk Regal waveform technology).
- C67ML Carta2+ / na? - 1448x1072 300dpi Carta Plus screen (=Carta HD) with Snow Field technology support
Premium Readers (Kepler Series)
- Kepler Pro / Monte Cristo
For a "premium" model there seems to be a suprising lack of information about the specs available from the distributor. According to the announcement from some Chinese stores, there should be Kepler Light, Kepler and Kepler Pro models, however they all seem to sell just the "Kepler Pro".
