I can only cringe when I read the origianl question. Break the bank??? None of them will break the bank. Some cost more than others and have certain advantages. Depends on how many options you want. Break the bank. Break your neck. You take your pick.

Why do so many people want to scrimp on the most important piece of equipment they will ever use for treestand hunting? Buy an SOP at the very least. Hunter's Safety System is easier and neater, but costs a few bucks more.
