I've been T1 for 16years, except for a brief 3month trial of the pump in Oct-Dec 2009, I have been on shots all my life.
The pump was more inconvenient for me, and caused my control to become worse, than shots so my endo and I decided I should switch back. There can be some advantages to the pump, but like with using shots, it's all personal preference. It might work for the kids at his camp, but it might not work for him. It's a LOT more expensive and it is more work(in my mind after having one for three months) than shots because you have to worry about things like failed sites, etc. I personally went through a month supply of infusion sites in 2weeks because they kept ripping out while I was sleeping or catching on things or failing. I cried almost daily during the 3months I was on the pump due to stress from having it not be this "magical machine that would make everything better" like so many people say..and I'm not one to cry often at all.
The pump itself was fine, I had the Animas Ping, it was more having ti attached 24/7, having to worry about sites, where to put it, and my bloodsugars having no pattern so we couldn't pin-point a basal rate even hourly that would work more than one day before needing to be changed again.. etc etc that I had the problem with it.
I think if you went to an information session it would help you make a decision, in the end if you aren't sure..there's always the option of doing a saline trial to see how he handles the pump being attached and then moving onto a 3month insulin trial like I did.
My mom was really excited when I wanted to try the pump, after years of her and my endo asking if I wanted to and me flat out going "NO!" because like you, it freaked me out(those brochures with kids playing soccer with them on, the idea of them getting ripped out make me wanna throw up..and then when i experienced a site getting ripped out when i was running...it validated my fear haha) but after seeing me on insulin for just one week, she changed her mind. I was determined to give it the 3months at least before deciding..but she saw everything i went through(because i lived at home at the time so i could adjust to the pump without worrying about rent) and hated every moment of it. she doesn't hate the pump, thinks it's great for some people, but doesnt want to see me on it again until i am wanting to have a family and the technology has improved(same thing my endo said when i told him i wanted off, he agreed with me on going back to shots because the pump was failing so bad for me)
A CGM is similar to the pump if only because you need to keep a small computer on your persons at all times and there's also an infusion site type needle that stays in the body. CGM's are wireless though, so there is no tubing to worry about. From what I understand, you still need to worry about hitting nerves or getting a bad spot, but it's not as damaging as having a pump site fail.
I am actually going to my endo today to discuss getting a CGM to help me gain better control. Sadly, in Canada the only CGM option is the MM Guardian, though I'd much rather get a Dexcom.
