I currently am using a FastBloc LE for hardware write blocking when acquiring drives and am in the market for another write blocker. I'm interested in any devices that you currently use or have used in the past that you would purchase again, and those that you would never use again even if it was given to you.

Below are some devices I have been looking at.

This one looks promising for write blocking flash cards, now if they would only make something similar for USB drives. (I know XP SP2 gives the ability to disable write operations to any connected USB device, but I don't use that for acquisition.)

The price for this device is almost too good to be true, anybody ever used one?

Finally I am interested in recomendations for purchasing a high quality SATA to EIDE converter/adapter. I have not yet had to acquire a SATA drive, but that is only a matter of time.
