Are there any Goodwill-type stores near you? You should be able to find lightly used cassette players there. Take a cassette tape with you to test the player.

I need to get a shingles shot; and after the pandemic, a trip to the dentist.

For leverage try a car jack. If the post has a crossbar (or a hole through which you can slide a pipe), two car jacks that you can crank up in tandem.

I thought people stick some kind of rubber stickers into their tubs/showers. My old 70's era avocado-green toilet has butterfly-shaped ones on the reservoir. Came with the house.

Happy Lunar New Year. ^_^
