I picked up one of these:
www.radioshack.com/product/index.jsp?productId=2179604.
As posted by CBWX34.
I like it due to its using common AAA batteries. I also think that it provides noticeably more magnification than the 60 to 100X unit that I linked to and all of the others too. I got the other ones out and compared them directly (I have all of the units that I linked to). I think it cost just under $15 at a Radio Shack here locally after taxes. The one thing I question, and likely why it has batteries with more capacity, is the fact that it uses an incandescent lamp. That means it uses more power and is not as bright at the LED lamps. In this appplication it still gives enough light for the task, and is a bit more "floody" which can be an advantage, but I worry about replacing the bulb when it burns out. LEDs with a lifetime of around 40 to 50 K hours, likely will never have this problem in normal use. it is probably 30% larger and a bit heavier than the one from Ebay. This is proably a plus here, it is a bit easier to hold steady.

Anyway Fred, If you have a Radio Shack close to you, you can check online to see if they have one, and you can get something fast and cheap with lots of magnification to start checking things out. No endorsement or recommendation meant...just saying, they are available and cheap and work OK.

Have used mine for over 5 years now,,,so far so good on the bulb!

I did recently get an LED one... at first the light seemed "overpowering". But now I'm getting used to it. Just don't know about the batteries yet. I still seem to pick up things better with the old one... but that could just be a lack of time with the LED.

Either one should give excellent results... just take the time to get used to it. :)

... the batteries in mine started going dim... I couldn't find "SG3" batteries it said it took, so I did a bit of research and found these on Amazon that were comparable ... and 50 for just over $5.00.

Got 'em in, they work! :woohoo:

For the price it's decent enough... I can easily see any issues on the blade. Depth of field isn't that great, so you have to move it around a bit to see everything, and you see the image "backwards", so that takes some getting used to. Maybe because it was what I started with, I just got used to these issues (or didn't know any better)... but there are those who get one and can't stand these issues, especially the backwards one.

I've been using the one Clay uses lately...

I'm not sure it's really 60x... but the clarity is much better... especially if you're trying to compare the finish (scratches) a stone leaves. And you can also see any issues on the edge.

Of course, it takes a different battery.... :S

I've tried 3 or 4 in the past year and the one Curtis recommends is IMHO definitely the best! Unless you want to use a "real" microscope... (I use the VEHO and I like it, but its depth of field is extremely narrow.)
