The zipper has been busted on my waders for the last couple of years, but they have still worked alright for my hunting. Yesterday, I went out and now have a leaky boot and a seep in the crotch.

So, new waders are in order.
I definitely can't afford, or justify $300 waders. I might be able to go $200, and I have some Cabelas bucks to use.
How do I use waders? I pretty much only duck hunt with them, I don't do any warm weather fly fishing or anything like that. I need waders with boots, insulated are good, but they probably don't have to be ultra-insulated.
I've always had neoprene, 5mm, usually, but would not eliminate breathables. They seem to be usually out of my price range though.
Does anyone have any suggestions? Durable waders you've been happy with? It would be nice to have something last more than three or four duck seasons.
Thanks
