Looking at these reels, there are the 'regular' ones, the 'delux' ones, and the 'professional' ones. Other than price, what is the difference? The professional one looks a little heavier (thicker wire), but the regular and delux ones look the same to me. I'm assuming that it doesn't really matter, and the regular one for $10 is just as good as the professional one for $50. I thought I better ask though... I can't see how the professional one could be "5 times better". Is there any real reason why you would need the professional one over the regular one?
