pop out boards

I have been looking to get a new board. I am not a great surfer so I am scared to go with fiberglass. I would kill it putting in my truck let alone in the water. I have a used bic which is what I am learning on. I don't know if I should keep trying to advance on this board or go with something else. I was looking into epoxy but a lot of people say they are harder to surf on than a real fiberglass board. Any advice? Also I have been to my surfshop and they are loaded with popout boards why are some people negative about these boards. If someone is learning to surf wouldn't a cheap popout be the way to go? I couldn't imagine paying a shaper to make a board for me that I would destroy learning on. Thanks
