Depends on what you are using it on and the chain itself, some of the most expensive chains I have ever used were also the shortest lived. They were designed to be extremely lightweight, and as a compromise wore very quickly.
I have a couple of $5 1/8" chains on IGH bikes that have seen over 10,000 miles of service. I have noticed that the OEM chain on my 1972 Raleigh Superbe is about 1/3 heavier than the current replacement chains I have been buying.
