It's all about what you like. I do hours of research usually before buying a new addition. And yes I have rehomed many after realizing I was in over my head or didn't enjoy the animal as much as I thought I would. I.E. the 14 foot burm I rescued years ago. Seemed like a good idea at the time but a couple months of wrestling her and almost losing more than once I decided maybe I should have started off with a baby so I traded her to a breeder for a hatchling. Lol. I'm staying with balls and leopard geckos as the main staples in my breeding collection because of the variety. However the wife and I seem to have a contest to see who can bring home the next strange and challenging thing. She brought home a couple stepped runner lizards last week and a tarantulla the other day. So now I get to confront my fear of spiders. And today I took in an orphaned squirrel the neighborhood kids rescued. Atleast til I can get a hold of a wildlife rehabilitation center. So really it all comes down to what can you handle, enjoy, and care for with out putting you or the animal at risk. Sorry for all the rambling I just remember being where you are now but I didn't have internet or local reptile nerds to ask for help. Lol good luck in what ever path you choose.
