Thanks Amigakit - you guys are on my radar, I'm just aware that the hardware component (or components that look similar) can be found on eBay for a little less.
I hoping to check whether 'any old' PCMCIA reader will work or only specific versions - type 1 or 2?
I've found an old PCMCIA network card at home, unlikely I'd need it on my A1200 but it doesn't actually slide into the slot. Something seems to be blocking it before it reaches the pins. Which then made me doubt any card reader would fit...
Sometimes you just have to bite the bullet and pay for the premium product and the peace-of-mind that comes with that.
