Old Kenmore appliances used to usually be manufactured by Whirlpool in the US. The prefix on the model number designates who actually makes Kenmore appliances, 110 is Whirlpool. They got a good reputation because Whirlpool usually makes decent stuff in the US, some of the higher end stuff is made in Korea, not as good or long lasting.
In the past 10 years, Sears has pretty much gone to the lowest bidder for their appliances and quality lacks, even in their higher end stuff. Korean made appliances tend to have much higher part costs and often a delay in getting some parts.
There is absolutely no need for 99% of people to buy a high end dryer, in the end, they heat to around 200-220 F and tumble at 40 PRM, a basic Whirlpool dryer will last for decades and you can buy a rebuild kit for peanuts that comes with the belt, drum rollers, clips, and tension pulley assy.
