- So far I am very happy with my Wren II. This drive runs so smoothly that
- I can't even tell that the head is moving when it reads & writes. If you
- are interested write or call:

- I'm one of the first individuals to have the opportunity to buy directly from
- this OEM. The refurbished status of these drives is the way around the
- "distributor only" sales policy of CDC. These disk drives should operate as
- new ones, and they do come with a 90 day warrenty. If you are interested in
- finding out the latest status of a refurbished Wren II give my RCP/M a call.
