I love the cheap 15 ft ladderstands. I've killed a ton of deer with bow and gun with them. Don't let some telll you they will not work. Just make sure your ourline is broken up with cover behind you.
Why would he care if you use a lock on type stand? There would be no damage as long as you take it down at the end of season. I have also used steps made from 4x4 blocks that are attacked with ropes. No damage at all.
