I know this thread is old but since its stickied, I thought I would say my two cents.
Some have pointed out that "expensive pieces" break just as easily, but I'd like to point out that just because you paid a high price for something doesn't mean you're getting quality. If your expensive glass is breaking just as easily as cheap, crappy glass, you're probably simply being overcharged for something that is in reality, cheap, crappy glass. As others have pointed out, just because its American made doesn't mean its quality made. Properly blown/made borosilicate glass is surprisingly tough - that's why its used in laboratory glassware. Quartz, which is pure Silica glass without any additives, is even tougher, hence its use in concentrate nails (and infrared patio heaters). Most cheap convenience store glass even borosilicate. If you're lucky, its just very thick soda-lime glass, and it might not even be that. I've seen some scary thin pieces, including one that was nearly paper thin and coated with a colored film to give it the appearance of colored glass.
I have a custom borosilicate piece I got directly from the blower 4 or 5 years ago for a great price. You don't need to spend an arm and a leg to get quality, you just need to do some shopping around. I've since dropped the piece many times, and have even kicked it across the room once and there's not even a single chip on it. I've had crappy convenience store glass randomly shatter for no apparent reason... most likely due to stress cracks from improper manufacturing.
Yes, China makes high-quality products, but most of that stuff isn't for the export market. The few skilled Chinese glassblowers making pipes, bongs, etc. in China sell to the local market, they're not pumping them out in mass quantities to be sold at your local K-Mart. That stuff is virtually all crap. Chinese glass blowers living in America? That's a different story. That's not Chinese made, its American made by someone who happens to be Chinese in nationality.
Also, I don't see how its "dumb" to spend more for something locally made that will likely last a lot longer. I think it's much less sensible to send your money overseas where its most likely supporting child labor instead of our own economy.
