What's the best first invertebrate "pet"?

Cool about the mantises. I'll look into it.

The millipedes - does it harm them in any way when our hands remove some of their natural oil?

Thanks all! I love reading all your responses. I am starting to warm up to hissing cockroaches, but only very slowly. I saw them at a pet store for $8 the other day. How much are they at shows usually? $2?

eight dollars is a bit high... I generally see them listed at $2 each. I got my two for free from someone who had a colony.
