I think if you're willing to put in the time and money, you should get a chameleon.

My veiled was my first reptile, you just have to do the research (this place is THE place to learn), and get over the bug thing. Once you have everything setup properly, they're not difficult to care for.
I don't like condemning animals to death either. Moths are my favourite insect, but for the sake of my cham, I've mustered up what it takes to feed him hornworms - which are cute caterpillars that turn into cool little moths. Same with silkies - those moths are way too cute

I like to think of it in a couple different ways. Most insects do not have brains like the mammals we think of - they don't have emotions and do not feel sorry for themselves, or their suddenly missing mates. If anything, with all the different types of food you have to feed these darn things, you'd be giving them a great quality of life before the inevitable happens.
Nature is a beautiful but crazy biotch, but without her and her ways, we and the animals we love so dearly wouldn't exist. The ultimate goal of a good chameleon owner is to emulate as natural an environment as we can. That includes feeding bugs.
The cool thing about veileds is that a lot of them will eat vegetation. Mine loves strawberries, and will take small slices of it right out of my fingers. It's so funny
