Motor vehicles. Major appliances, such as dishwashers and washer/dryers. Canon cameras and lenses.
I can't think of too many other things that offer much in the way of repair. Consider a flat panel TV. Paid $1200 for it three years ago? Think there are spare parts for it? A laptop about the same age?
Homeowners in the USA know how incredibly difficult it is to find a handyman. Mostly, if we want to repair something around the house, we pay through the nose for half-assed work, or we Google, go to a mega-hardware store, and do it ourselves.
Consumers have largely accepted the idea of replacing instead of repairing.
Generally, I can find parts and do my own. I had a 1 yr old towel heater fail a week or so ago, they sent a replacement and said scrap the old one. Got the replacement last night. Its welded together very fine welds in 20 places on the stainless tubing. I've been thinking I'd see if a dremel can cut those welds so I can figure out where the heating cable failed. Its 300 stainless, so that may be too much for my dremel. I can use my big DeWalt grinder or my jugsaw, but run the risk of cutting the cable inside. The welds are 1/2 inch long, about 1/6 the circumference of the tubes, but there are 20 of them.
I had a antenna jack break off my 6 year old Flat panel TV. I can find a new board, but not the 2 cent part that broke. Even if I did find it, its inside the tuner, and thats soldered all around, so a huge job to unsolder. I have the tool with the suction bulb, so it might work. A replacement board cost $100 and up, and a NEW TV equal to my old one that cost $800 new is now $300 and its better. The old TV is now used as a monitor and for watching online programs, its just the antenna that doesn't work. Our goat got caught in the antenna lead and pulled it apart. I had the cable fenced off, but someone took it down.
I've repaired multiple laptops, almost everything in them can be repaired or replaced, new screen, new keyboard, new drives, new radio, memory and so on. Some parts like the main board have the processor soldered on and might be a hassle to find, but I'm pretty sure I could find one. The issue is that they become obsolete so quickly, so by the time they fail, they are not worth the cost to repair.
