The logs that you linked to are about 50% higher than I expected...
I believe they are talking tops... all real log people understand this.
You need to find where they get their logs...
I paid $200 bucks for a 12 inch 40 foot log... Which I believe is the ideal size.
The really low prices for logs comes from someone that does not value them like the government bug killed or fire killed logs.
My logs were from a tree farm where they really like logs, hence I paid $925 for a 1000 board feet...

OBTW, one member used bug killed logs and they were great!
