How hard or easy they are to hook up is subjective and will vary based on a person's handiness with doing this kind of work. I feel they are well designed and made and that installation is relatively easy if you take your time and follow the instructions. There is more assembly with the Bull Frog Manual Turnout Control unit whereas the Blue Point unit comes assembled. Complexity also depends on where and how they are being installed - at what angle to the layout fascia, how far away, wiring or platform supports that may be in the way, etc.
I do not know about throwing two switches manually at once.
