Glide computer review

I'm looking for a ship to buy and find that I don't have much
perspective in evaluating various glide computers. Is there an
existing and comprehensive glide computer review?

My doubtlessly flawed view of the glide computer universe divides
things into two main groups - panel mounted and PDA-based. Another
way to divide things might be between moving map and non-moving map
systems. I'm sure the type of flying is an important in this choice -
contests vs. general XC flying for example.

At the least, I'm hoping for some guidance to distinguish the
Cambridge 302 and the Ilec SN-10B. What else deserves to be
evaluated? Also, are things moving in a particular direction -- like
large super bright (vs. PDA's) built in displays? Having components
that would be useful for doing that later would be plus.

I value: ease of use, readability in sunlight, the ability to monitor
multiple landing options simultaneously, no 250 turn point limitation
(L-Nav), and reliable wind data. I like to fly into areas I've never
been to before and haven't done contests - but might.

Thanks to all who will take a crack at this,

Eric
