I have three 15' stands that I bought for about $50 each at Dick's. They are not very comfortable (I REALLY wish that they had a flip up seat), but they are left in places where they could be stolen, so I did not want to spend too much.

I like the convenience of arriving, climbing the ladder, hooking my safety strap, and I am ready to hunt. Also, many trees where I hunt are not climbable (some are not even suitable for a hang-on stand), but the ladder stands still work.
