Well I just got my LA roller back from Ken at Oregon two weeks ago. The cost to regrind my core was 219.00 plus shipping and tax. Ken is 77 yrs. old, so it will take a month to get done, He is a Great guy to talk to and I highly recommend him, I've had several done by him,( all rollers.) Shipping was 25.00 one way from WI. So there you have it, the latest pricing. I don't know where these guys saying it's $75-100 are living?? maybe 10 years ago?
