Granted that more expensive doesn't always mean better quality but 9/10 times it does.
You can get a nice API ladder stand for about $140. I have one on the front of the left side of my property and it seems very sturdy.
Took some 2x4's and built a shooting rail/safety rail (cause it's open all the way around) and I've been satisfied so far.
I like ladder stands cause you can put em' up and leave em' (if you hunt private property).
