I found a compromise at Amazon. This 10x, 21mm triplet loupe gets almost 5 stars from reviewers but is under $20.00. Click here for Amazon Link.
This loupe gives you good quality and I am deliberately not adding "for the price". It's good quality, period. Read the Amazon reviews; you usually don't see that degree of satisfaction until you reach twice the price.
The LED's switch on with an easy to operate slide switch. That's likely to last much longer than a button.
With LED's ON
I had never owned an LED loupe before this. Now that I have, I wouldn't consider anything else. Of course you don't have to switch on the lights if you have good illumination from elsewhere, but when you don't have good lighting, this is a life saver (well, a money saver or a money finder, depending on the circumstance). It takes a watch style battery and it's easy to change when that becomes necessary,
The lights do wash out colors, but they eliminate shadows and let you see when you would otherwise have been cursing.
I recommend this highly. Shipment was slow, but worth the wait.
Note: All my coins are in a safe deposit box. I keep nothing in my home.
