I looked online at the cheap ones at Harbor Freight a few minutes ago. They've got theirs on sale for $3.99 this week, but it's just a standard visor model without lights or any extra lenses. I might run by there tomorrow and pick one up just to see if I like the way that it works. I know they aren't top notch quality, but for less than five bucks it will give me an idea of whether the visor is the way that I want to go or not, without investing a lot of money in it from the git-go.
And if I like the way that it works, I'll look into getting a better one, with interchangeable lenses and lights down the road, when money isn't as tight.
Thanks
