As previously stated I would rent one for a few weekends first and make sure the juice is worth the squeeze. I bought one four years ago when my wife said she’d enjoy weekends away. 2 more baby’s later and we used it all of three weekends in three years. Sold it last year for a loss.
I've had two razors, had to send the first in because the zoom knob broke when I borrowed it to my brother, the second was significantly more clear. I don't know anything about the Ares but i'd rather not need the warranty then have to send a spotting scope in during the rut.
