Thanks for the tip on looking at chit!I pretty much just use 100 X and leave it there. Eggs and cocci are very easy to see at that range. I would love to have one with the video screen, that would relieve a lot of eye strain. It just depends on how many fecals you plan to be looking at, I generally do two to four per week but when you first start out you will be spending lots of time looking at ****.
