Ok I saw the post from a few weeks ago comparing the helix 10 to the 899 it looks like the helix is the way to go. On paper the specs look almost identical. Is the 7 and the 899 the exact same screen size?
I have 2 -788 hd di with around 30 hours on both. I may keep one unit to have a dedicated di unit since it looks like the di on the si unit isn't that great. Thoughts or input appreciated.
