Today's bearings are much better than they used to be. Price doesn't always translate to quality. As an example, on daughter's Honda Civic tensioner bearing failed. Replaced it with a $17 bearing from NAPA, which lasted less than six months. Replaced that bearing with a $1.99 bearing from Fastenal, which now has over 300K miles on it. FYI, bearing is a 6203 2RS, same as in saw. The 6203 is probably the most common bearing in usage in the world.
