RFID Reader library

Using Arduino General Electronics
#1

Does anyone know of a library for a MF522-AN RFID reader? I recently bought one off ebay and looking at the example code confused me. A lot.
This is the reader: http://www.ebay.co.uk/itm/RFID-13-56Mhz-Module-Tags-SPI-Interface-Read-Write-for-Arduino-UNO-R3-Mega-MCU-/170859728113?pt=UK_Computing_Other_Computing_Networking&hash=item27c8088cf1#ht_2473wt_1271 and they can be found all over ebay...

If any of you guys think it would be easier to just buy a Parallax or a Sparkfun reader, leave me a comment...

A simple google search for 'arduino MF522-AN' yields many results and the top one How to get started with the Mifare MF522-AN and Arduino – Grant Gibson might be a good starting point.
