Hi Vince; are you sure you really need 20X? I had a dual 10 and 20 for some years and I don't think that I used the 20X more than once because it was so difficult getting enough light - I had to hold it so close to my eye that it was almost impossible to see anything. I suppose that an illuminated 20X might work but you can see most things you need to see with 10X.
Eventually the 10X lens fell out, by the way. I now have an 8X which is perfect.The illuminated ones are fine but I don't think there's an illuminated 20X available at reasonable price anyhow.
Cheers, Alan
