I have my Summit Viper X4 climber that I use 90% of the time. It has held up to everything and is very rugged but yet lightweight.

I also bought an old used15' ladder stand from a co-worker for $20 bucks. He no longer hunts, and the ladder stand just sat in his shed for years. It's still looks okay, no signs of damage, no rust, etc... but, it's real heavy gauge steel and would be a monster to try packing into the woods. I just gotta figure out what to do with it and where I can set it up permanently.
