If you plan ahead, and watch for sales, standard size, pre-made loops are often less expensive than buying full reels. Even my STIHL dealer told me that at his wholesale cost, it was not worth his time to spin standard loops of chain, although, he kept several reels for custom lengths. Some dealers offer '
buy one get one' or '
buy 2 and get one' deals periodically. Bailey's offers '
10 loops for $100' periodically for their re-branded Carlton chains. But full reels are sometimes the only way to find very specific types of chain (cutter type, sequence, etc.) if you are picky.
My spinner and breaker have paid for themselves many times over, repairing damaged chain, and resizing chain loops to fit other saws. 10 good, 'free' chains and I am even. I often get good, used loops cheap at garage and estate sales, and have bought an number on eBay. I have re-sized a number of loops for friends.
With a file, screwdriver, and hammer, along with a few presets,you can break and 'mend' chain; but it won't be pretty, or efficient. A lot of old school cutters carried a chain anvil and punch for field repairs - this is the topic of a current thread on another forum. And some guys are into '
good enough' repairs. But with a basic, good quality breaker, you don't need to grind off rivet heads, and can reuse many tie straps (I don't reuse rivets). Same thing with a decent spinner: it can be hard to tell repairs apart from factory spun with a little practice.
Most of my spinner / breaker comments, and input from a lot of other guys, is in this thread:

I was hopeful, but not impressed. They have been around a long time. About the same cost as a bench spinner, and easier to carry in the field.
