I'm a former tool and mold maker and have made many gears over the years so I know what a quality gear looks like. Boston Gear has been making gears for years, but until now I haven't had to buy them. The two gears I bought for my home lathe are all I needed and expected from such a respected company. Not only the quality of the gears is evident, but also the packaging and delivery. You might not need gear very often, but while it's still in use, this is the place to get it!
