There are several different ones advertised in 80-MICRO for around $200 (He already has 2 Shugart SA200 disk drives).. These advertrisements do not say much about them, just that they include the controller, power-supply, mounting hardware, and cables... Has anybody used any, are they any 'gotchas' in using them, and are they any that I should stay away from... Any advice at all would be greatly appreciated...

We bought all of the electronics for the disk upgrade from an outfit called Micro Data Supplies in Euclid, Ohio. They have a package called a "Diskit". The disk controller board was the Micro Design MD-7 (or something like that). We bought the RS-232 board from the same outfit in Ohio. The diskit included the controller board, all cables (except a ground strap for the drives), two metal mounting plates for the drives, a drive power supply (switching type by Astec - almost identical to that used in the Model-III itself), and instructions. Everything plugged or screwed in, and it worked right away. The quality of all items seems very good, judging by appearance only. There have been no failures so far. This kit supports single or double-side drives, 5.25 or 8-inch, and both internal and external drives. The RS-232 board is a separate purchase. It too looks good, and worked right away. So far, the owner of the computer and I are very pleased with what we bought. The service on the order was within a week or two. I don't remember exactly, but it was fast.
