Any of those will work. The difference is the less expensive one you have won't last twenty years of use. A chain needs to be replaced every 2,000 to 5,000 miles of riding. That means you use the tool to press out a pin and push the replacement back in. So you can see unless you put lots of miles on the bike in extreme conditions with by hard riding, the tool doesn't get much use.
