Should have picked it up at the end of season icefishing sale in March, they were even cheaper then.
I won't tell you how much because I don't want to dissapoint you.
As for being in the wind. Just anchor one tether before setting it up and then anchor the other three.
It can be difficult to set up the first time or two out. Take time to look and see how it sets up and collapses and you will be fine.
It wil take three or four trials before you see exactly how it collapses back down.
The poles get broken by trying to force the shelter closed. When you get the hang of it, it will close just like one of those folding camp chairs.
When you put it away leave the windows detached, and place them in the carry bag last.
In cold weather they get stiff and if left attached and folded they can break.
