I just got this little "60X LED UV light pocket microscope jeweler currency magnifier adjustable loupe" in the mail from Amazon. It's micro sized and has a strong led side light that actually lights up what you are viewing and the view is sharp. For a cheap (less than $3, free shipping) little lighted scope, you can't beat this unit. Badass for a mini pocket scope. Highly recommended.
I won't link, but it's not hard to Google. Takes a month to get it, but at that price I couldn't believe the quality.
