Here's what I do when faced wtih a decision like this.
Flip a coin and, in your head, tell yourself that you're gonna do whatever the coin said to do. Live with that decision for 24 hours.
If it's the wrong decision, you'll know it. It'll nag at you. If you feel a sense of relief, the coin made the right decision for you.
When I'm on tenterhooks about a decision like this, the real hurdle for me is the fact that no decision has been made. My brain just bounces around and around the implications of two different sets of outcomes and never has a chance to think through a single scenario. Once a decision is made, regardless of whether it's the right one, I seem able to finally focus and organize the facts. It's a case of an emotional state affecting cognitives. Once you make a decision, the emotional subext can change dramatically.
Works for me every time. YMMV, but it's worth a try. Let me know if this works, if you do.
Unrelated: Why would you have to "schedule an implementation" for this device? In fact, what is it about this "implementation" that distinguishes it from the usual unboxing, connection, and configuration chores?
