I guess the SCSI card readers are getting harder to find and sell. I remember back in the day I got two Microtech PCD-47B's for $30 a piece off of eBay. Now just one of them goes for $200.
You gotta buy from JD when he has stock. It doesn't last forever. He closed the whole site down a while back when all supplies ran out, only to start it up again when he found new products. When he has what you want get in there and buy it. There's a lot of us looking for them.
