Hi Vaidya
I have the MEF 3 on my TSA 102 and I like it very much. It helps a lot at high powers. I can focus more carefully and not jiggle the scope so much as less force is required. It is not essential but very nice to have.
On the FC76DC I manage without one. I have mostly been using that scope for lower powers and grab and go observing.
