Hi,
Time ago I worked at a computer retail shop that happened to be an official Amiga dealer too. Occasionally, I worked on A500 mobos, usually soldering Chip RAM expansions on mobos with provision for it (Rev 6 I think). I remember having seen those Epson floppy drives. It was a long time ago, but I think I can still trust such memories. As I remember, those were quieter than the Chinon drives. I suppose that Epson produced them for Commodore at some time (and this is only a supposal).
At some point, I found that that some type of very cheap PC drive would work on the Amiga with a change in a jumper. We made some nice cash selling re-jumpered PC drives at Amiga-drive prices! The LED of the drive would flicker, but it worked fine for the rest. It could be that those Epson drives that you can get hold of work with minor changes. You try at your own risk.
Now, thinking about all this has brought back some memories.
I remember having seen A500 keyboards with only one Amiga key, on the right side of the space bar. On the left of the space bar they had a Commodore key, instead of the usual "solid-filled", left, Amiga key. That Commodore key had the Commodore logo on it, in the style of the C64 Commodore key.
Furthermore, I remember having seen A2000 keyboards with both sets of ALT and AMIGA keys at a distance from the space bar. They had a badge reading "AMIGA 2000" in italics. I think they were made by Cherry.
Regards.
