Information about the Acard AEC-7720U is available on Acard's website: <http://www.acard.com.tw/english/fb01-product.jsp?idno_no=23&prod_no=AEC-7720U&type1_title=SCSIDE%20Bridge&type1_idno=null> The 7720U includes mumble-HBA support so it does support large drives over 128 GB or 137 GB or whatever that limit is. Of course some older computers do not support partitions that large. For example, a 750 GB drive on a Mac SE/30 would need the drive broken into 375 partitions... I don't know if they combine shipping. $10 for shipping does seem excessive, especially since the things don't weigh anything. Also, those are used 7720Us and do not include the power dongle. However, the power dongle is simply a 'Y' splitter which terminates in a regular hard drive power connector and a floppy drive power connector. Your hard drive needs a power connector of course, and the 7720U draws its power That style of splitter is getting harder to find, but many of the folks on this list may have them on hand--or a regular two-hard drive splitter and a hard drive to floppy drive power adapter. Oh, and the Ebay guy doesn't ship internationally. I'm not trying to be discouraging; it's still a very good price, but there are some details buyers should be aware of. I feel free to point these things out since I sold the last of my *new* 7720Us ($39 + $4.85 shipping with power dongle) a couple of weeks ago. :-) Jeff Walther
