dont really want to go offtopic here becoz of the new market place rules
the ipods with biggest memory is currently the classic series has (the latest generation i.e. 6g) currently 2 versions, 80gb and 160gb and they are the rectangular shaped ones , they are available in black or silver color
officially they are available for ~18,000 for 80gb and ~26,000 , the price was increased by almost 3-4k in the last 1 month for some reason , although i think it was becoz of the increase in the dollar exchange rate, not sure
they come with full box and cables etc (except for the video one) and 1 year warranty
