Our Tour Guide while we were there was Gershon Preiwer (www.israelguide10.com) He is an incredible man and a great tour guide.
I found a radio interview with him on the internet. It is from a couple of years ago but it is good to hear him. I would encourage anyone ever planning a trip to Israel to try to have Gershon as your guide.
Here's a link to the page with the radio interview -- the interview is from 29.10.04:
