Zoom Eyepiece lens...

I'm going to be taking a trip to Florida in a few weeks and have a nice
little setup that I think I can bring as a "carry on" on a plane. Rather
than bother taking a complete eyepiece case, I was thinking about getting a
zoom eyepiece. They are not my notion of an ideal eyepiece, except in this
case where I don't want a lot of extra "stuff" to deal with on the plane.

Anyone have any good or bad experiences with these? I'm wondering if it
would be worth picking one up for the trip.

Thanks,

Mike.
