$29.90 http://www.4dsystems.com.au/prod.php?id=22 and read the user manual which is a link on the left of the screen.
Uses SD cards. A very simple serial command set. Any baud rate (auto locks on by initialising with a "U" at startup). Megabytes of storage. Does use 3V so needs resistors if running from 5V. But picaxe runs from 3V too. Write/Read a sector of 512 bytes or even write/read single bytes.
May almost be simpler for external storage than external eeprom, and the instruction set looks simple enough for even an 08M to run.
Is there a catch?
Addit: I just ordered one. It looks *so* much simpler than trying to bit bang SD cards or write IDE drivers. And with wireless links, only one board would need to have this large storage.
