I wish I lived close to you Steve and SCG.  I love to candle eggs.  I just use my little coleman max light flashlight and my hand.   I can see veins early even before day 7.  Day 7 to 14 I can see lots of cool things and veins.   Seeing movement it amazing.   You really have to get an eye for it.  I put the light in the palm of my left hand and make a circle with my fingers around the end of the light and then hold the egg up with my right hand and make a seal between my left hand and the egg on the aircell end.  Then I turn and move the egg with my right hand till I can see good.  I do this in the dark in the bathroom with the door closed so there is no outside light messing with my eyes.  Let me know if you need a picture of how I hold the light to the egg.  I could do that for you.
