Just some more on the quality debate. I think we get what we need w.r.t. product quality, based on what they are willing to pay. It's a a hard concept for a lot of engineer-types like me to grasp, but "good enough and cheap" is what sells in high volume so that's what Lowes and Home Depot stock. It's not so much a US vs. foreign thing, at least in my mind.
In a past life, I learned some interesting things about how small engine products are engineered - think string trimmers, etc. I may be a off on the exact numbers from memory, but generally this was the story:
The products for big box stores were designed to hit a <$100 price point and had a MTBF design of 17 operating hours. My first reaction was this was just outrageously short, but it was pointed out that the average buyer used the machine 20min/week for a 24week mowing season = 8hours/year. So consumer machines were designed to run for 2-3 years before needing service, and little engineering went into making them fixable.
Commercial products were designed for MTBF of 300 hours, but with a price point of >$300. Again, this was driven buy usage patterns based on 2h/day for a 24week mowing season = 240hours/year. So commercial machines were designed to go a full season before needing service, and were designed to be more easily serviced. Which is a good match for how they are used.
So why are big box stored full of inferior machines when 15X greater quality is available for 3X greater price? Because a lot of people don't need that quality and won't pay up-front for it. Lifecycle costs for the cheaper stuff are much higher, but pay-as-you-go is what most consumers choose rather than "investing" up front.
Then again, most people at Lowes or Home Depot don't research their purchase to death like we do here on TBN. So when they see the $99 Ryobi trimmer next to the $49 model, they think $99="premium product" and are bummed when it dies 3 years later. They have no idea that a more bulletproof $300 Stihl trimmer even exists.
