I've got the oregon breaker and spinner. They're well made and I've spun up maybe 5 or 6 100' rolls of chain on them the last year or so. I expect they'll last pretty much forever. Whatever you get, invest in a quality adjustable anvil. The one that comes with the breaker is awful, and you end up bending/twisting chain and may even have to grind the rivets a little before breaking them. With a quality adjustable anvil you can easily break the chains. I think that most spinners are similar in quality, but there's a difference in quality between breakers for sure.
