I have to agree that my experiences of israeli security are somewhat more involved than the OP's -- usually 1.5 - 2.5 hours. However, without exception, the security personnel are the most professional, courteous that I have ever met, so you almost don't mind.

And re: lying -- they ask the same question 5 different ways, so having a stack of lies ready-prepared might just be OK, otherwise you will get tripped up (can't see the point myself).

One thing that always amuses me: it takes 10 times longer to leave israel through TLV than to enter it!
