But none of this is going to help you because all LCDs to a greater or lesser extent have this problem in sunlight.
The only other option is to go for a cam with viewfinder but these tend to be much larger than the (quite a few now) cams you have been considering.
It's the Catch-22 of camcorders: too small and it has no viewfinder, too large and you'll never be prepared to carry it about with you.
I call it the "bog-roll conundrum": imagine you have just 25p in the world. You can buy a tin of beans or a toilet roll. If you don't buy the beans you don't need the toilet roll, but if you buy the toilet roll you don't need it. Buy the beans and..... well find some dock leaves.
