I recently subscribed to Sawmill & Woodlot magazine, but have only gotten one issue. It's a bit low on content, IMO, and heavy on advertising it seems to me. Seems like one of the best though...
I just looked through the Timberline digital version online, and I don't seem to be the target audience, not sure. Also heavy on advertising and low on content.
I saw a national monthly price list for various logs, but can't find it at the moment. I'm just going to stick with Sawmill & Woodlot mag, but always on the lookout for other options myself.
