Ameristep Doghouse blinds are good quality and cheap. I have three and they last for about 4 years out in the field for 4 months a year. Had a damn feral cat or raccoon tear one all up one time though.
I've got several of these that have to be at least 15 years old. One thing that might have made them last is that I treated them with a waterproof spray when I got them. I always take them up after the season and store them in the house. They are getting ragged and will have to be replaced soon, but they can last a long time if you take care of them.
