http://www.sandisk.com/Products/Catalog(1240)-SanDisk_Extreme_Readers.aspx I'm using the 8gig Extreme III with the USB reader.
http://www.provantage.com/sandisk-sddr-92-a15~7SNDK29M.htm This is the 3rd card reader model I have purchased, and by far the best. It is very fast, and very accurate. Not to mention it's only $14.30.
Forget all those... Your G5 has a firewire 800 port. Use it.. http://www.lexar.com/readers/pro_udma_reader.html
