Spinning wheels

I am starting to think about getting myself a spinning wheel. And , as with almost every other purchase of more than $100, I want to do research and have peoples opinion. I am looking for something that is easily portable, something that will not take up too much space when stored, and something with bobbins that I can get a fair amount of yarn. Spinning really fine yarn is not an issue for me right now, but it may become in the future. Who knows?

What do you spin on and what do you like and dislike about it? Is there a type of wheel that you would like to have and why?

Thanks in advance.
