Well, there's a pretty wide variety of herps that do not require insects. Most snakes, obviously, eat only rodents.
Here's some other suggestions that primarily eat prepared food or vegetation:
green iguanas
uromastyx
blue-tongued skinks
crested & gargoyle geckos (only as adults...babies do eat insects)
most tortoise species
box turtles
ornate wood turtles
Also, in case you didn't know, crickets aren't the only option for insectivores. Many of the "worms" (most are actually beetle larvae) don't hop around and escape easily, as well as the smell factor isn't as bad. These include mealworms, superworms, waxworms, night crawlers, and red wigglers. So if you didn't mind these little crawlies, then your options open up tremendously.
