A few thoughts:
1) installing the transmitter itself is pretty simple. Just unscrew the high pressure port screw with an allen wrench (most are 5/32" but there are some odd ball sizes out there. Screw in the transmitter and use a wrench on the metal fitting (a small cresent wrench is fine as long as it is flat/thin enough to fit between the transmitter and the regulator.) Choke up on it and just tighten it just past hand tight - maybe 1/16 of a turn.
2) Lynn sates it well in terms of how you should approach your LDS and how your relationship with them should work. I've never understood the incredibly competitive nature of dives shops that often won't talk to each other or refer customers to one another, and extend that to you by getting upset if you frequent another shop. It's not like you are married to one and having sex with the other.
3) For awhile back in the day when I assisted with classes, i used an air integrated computer, and I had a few failures over time related to both batteries losing voltage in cold temperatures and to pressure sensor failures and errors - one that just quit and another that read 245 psi high (i.e. it read 245 psi when not connected to a tank).
If you are only doing no decompression diving and monitor your SPG intelligently, you'll be able to spot when it "sticks" or fails and you'll be able to end the dive. However if it dies on day one of a live aboard boat trip, you could be SOL unless the boat has a spare. Consequently, for anyone doing deco diving or taking a trip, I suggest they have a spare SPG available.
