but someone said the pre-made loops at Bailey's are the same or lower price of bulk? Perhaps in SOME pitches, . . .
Absolutely.
You have to be a careful shopper if you are trying to get the best price. And, you also need to figure in the costs of shipping, as well as your time, etc. Depends on the popularity of the chain, the length of the loops (drive link count), etc. Also, depends upon how picky you are about brand (STIHL, Oregon, Carlton, WoodlandPro, etc.), and how many loops you actually need.
If you are planning on making your own, I would recommend investing in a bench mount spinner and breaker set over the Granberg tool. You can get a modest set for a little over $100. from places like Bailey's. The Granberg is more of a field repair tool - do a search and check out members's comments about using it for more than occasional use.
