the 8oz espro is too tiny. good only for people who makes 1 tiny cup of french press.
besides, the biggest 32oz doesn't mean you HAVE to make 32oz of coffee. so i would rather go with the biggest.
I do agree, just that my preference is for the 18oz. I wouldn't complain if the drop was for the 32oz, but I wouldn't buy the 8oz. I have an 8oz french press currently and I wish it was bigger.
