Did a bunch of reading. Went eaney meaney miney moe and ordered a competition electronics pro. I can upgrade with a remote if I like it and Midway will take it back if I dont like it. If it doesnt work out I think Ill spring for the Oehler 35. Sounds like chronographs can be very sensitive to light conditions, muzzle blast, bad wires, poor quality control, low batteries, and day of the week... Ughh..
