I hit my local hamfest today and was taken by surprise. A dealer that specializes in antenna hardware had Harken blocks for sale. Maybe this isn't new, but it was to me. It also seemed like overkill. I have used cheap pulleys for years. I think it would be crying time if a $50 block was stuck way up in a tree. The dealer caught me checking prices online. I had to chuckle; West was cheaper.
