Panasonic JU-253 Disk Drive (Very High Quality)
You're kidding (rhetorical question, I know he is not)
The Matu-Shita/Panasonic is the brand of Amiga-drives you MUST avoid at all costs (but afaik the where only build into early A2000/500 and some A1000s).
Chinon is the most common and o.k., my A500 even came with a TEAC (sweet), and the C=-made had an Epson inside which was also o.k.
I only had 1 Matushita in a 2nd hand A2000, and the noise it made was far to much to trust it with any disk (and yes the drive was "o.k", thats just the way they "work").
I even remember a certain piece of HW that allowed you to make "backups" of copy-protected disks being advertised as "works with all Amiga-drives except Matushita".
