Do you have a small 6x30 finder?
Here is nice lens you can use to make a nifty 50mm finder!!
The lens is from a Bushnell bino. The lens is multi-coated, cemented and is somewhere around f3.6 to 4.
I used the other lens from the pair to make myself 50mm finder.
All you need is 2-3 different plumbing tubings (very cheap) and the eyepiece from your 6x30
There is no need to drill holes and put screws for attaching tube, the tubing fits firmly onto each other if you choose the right ones.
SEE the pic of the finder I made using pvc tubing and the eyepiece from my celestron 6x30.

You will receive what you see in the first picture.
$15 US shipping $2!!!!!
