Well I got a hold of a FireWire400 Lexar professional CF card reader for my MacBookPro so I'm back up with that....

I already used google search. I mostly found links referencing pages that didn't exist or reposts of the same pages and links to online stores that used to offer the service but do not anymore.

If all this mod is doing is cutting the card cage for a card to fit, I don't need that as the card fits the cage as is already.
