Hi! I was just wondering if any of you could recommend a cheaper alternative to nifty minidrive which fits the retina 13. On ebay there´s different cheaper versions of nifty minidrive but they don't work with the retina 13. (Needs to be smaller than for air, retina 15 etc.) I could only find one that fits with the retina 13 and thats the nifty mini drive which is quiet expensive, (its just an adapter!) Guess the others will work but they will probably stick out so it will be easy to break. Thanks in advance.
