Check your local pawn shops. Just found out recently that the guy at the pond shop in my area knows nothing about tree stands. They aren't the nicest climbers but he priced all 3 for $25 a piece. I'll be back in a few days to pick them up. I like to leave mine on the tree so this would work well for me, and I'm broke.
But if you have the money if definitely spend the cash and buy a nice climber. Ive heard nothing but good things about the summit viper. Only bad thing being that it's so comfortable it's hard to stay awake in it lol
