Not all Sanyo Fisher was crap, it's really odd but they put some decent marketing muscle behind the boomboxes and stereo microcassette lines and made some nicer models. I think I have most of the microcassette line of portables including the PH-M20, the PH-25, and the two kangaroo boomboxes (boomboxes with plug in tape units), M-88 and M-x66, there might be some more I'm forgetting. Some of these were the cream of the crop for stereo microcassette, some had Sanyo Versions for other world markets, but most were branded Fisher. I think Sears went with Sharp for stereo microcassette found in their two TV/Boombox/with plug in stereo microcassette tape unit
I've bought some Sears LXI Mini Systems by Sanyo, they fly under the radar and are nice beefy little units. If you can get a full stack for cheap they make nice desk top stereos and can even get decently loud. They definately look nice and would be similar to the AIWA 22 Series. I've never run across Fisher by Sears, by the early 80's USA Fisher was #1 for flimsy all-in-one systems, every girl owned one and it was the beginning of the end for the golden age of stereo.
I love zombie threads, it just shows how much interest there is in all of this equipment.
