That price is pretty reasonable, IMHO, but...

As I read the description, I am concenred about what size drives the adapter really takes, and how big the resulting "new drive" is. They seem to have mixed the descriptions between their 2.5" adapter (above link) and their 3.5" adapter (http://online.century.co.jp/BittradeTest/e_shop/chb35int.html) - they refer to the 3.5" part in the 2.5" description.

As I recall, for most installations, you would want an adapter that would attach to a 2.5" laptop drive and increase the thickness of the drive+adapter to no more than 17mm. This adapter would take a 9.5mm drive and make it a 21.5mm thick drive - which may be fine for some applications, but for drives that need to be installed in HD trays, it may be too big...

I do not need any of these, as I can't think of any machines I plan to run that use 50 pin SCSI drives - if it was an adapter to take 2.5" laptop IDE drives and adapt them to SCA I might be interested...
