That looks like a great package. The lighted sun screens can be a big plus. These days pretty much all artificial light (fluorescent, sodium vapor, etc) flickers at 120Hz and makes the chronograph useless. I assume the lighted sunscreens would make it usable at indoor ranges or outdoor ones at night.
As far as accuracy goes, I'm an electrical engineer and design similar stuff to what's inside these chronographs. The really expensive ones are no more accurate than the cheap ones. It's all digital logic and super accurate crystal timebases. I have a cheap 15 year old Chrony that's just as accurate as a top end Oehler. Build quality and software are about the only differences you'll notice.
