Meh. It'll help a bit, but I don't think the real savings are near what people are expecting.
Cheaper new cranks and cases. Yay! But only if you need them. Which you probably don't. If your parts were scrap it would make sense to buy new for a couple hundred more than buying overhauled outright. But most likely your parts need minor repairs. So do you get your crank ground and certified for $500 or buy new for a few thousand more? Your case overhauled for $1000 or new for $4500?
The biggest savings are for people that run until failure and then get charged though the nose for replacing all their unusable parts. Gaskets, bearings, cams, cylinder kits and normal wear items probably won't change much.
“Just overnight, the industry lost about a million dollars on that deal” said Zephyr. That's a drop in the bucket when spread out over dozens of shops each carrying a couple million in parts.
