best 2oooXL internal card reader

does anyone have a tip of what is the best card reader model for the XL and where you can get them cheaper than V.s.t or the Ebay set ups. I was thinking I could get one around 40 or 50 bucks at the computer store if i knew the specifications of the AKAI compatible ones. I read Midicase's model#'s and checked Akaipro for specs but couldnt find them there. I dont want to buy one for 30 or 4o and it not work. Whats the best spot for these card readers, or are they becoming a commodity and not availible in many places anymore. Every card reader google brings up is USB unless its a akai dealer trying to sell them overprice.


or am i just wrong.
Let me know if you know more than me
