I was just using round numbers for overall mill package discussion. But my guesstimate 575 CDN (for Taiwan Align FOB Calgary) less my guesstimate ~30% less for Chinese equivalent = 402$ CDN. Not much different than your ~$400 apples to apples. For sure everyone should check around, prices vary over time, often by the same distributors.
Reading some posts ~5 years ago, lots of guys were having issues with Chinese powerfeeds, mainly electronics. The electrical savvy guys showed where they cut corners on components. Then they couldn't find Lucky Lucy's Purses & Mill Accessories Ebay storefront for warranty or parts. (That was a joke). But like many things, they have generally improved over time...although you never really know whats inside unless that's your forte. I had an Ebay Chinese PF on my RF-45, worked fine for the several years I had it, no issues.
