low capacity SD cards

Why so small? Newegg doesn't even have anything smaller than 1GB in stock.

Here's a 1GB card for $3.75 -

for that price, I'll settle. Why so small? the internal 16mb memory is supposed to hold over 50 photos. but if the batteries goes dead, so does the photos unless its on a SD card. and really anything over 32-64mb is far overkill, but if the price is right.....

i got a 32mb card but you really should just get it from neweggg
