Hey guys, seems like I may have found the right spot.... I a 20 year old from Iowa. Probably wondering where that is...

Anyways I'm looking for a new pet. I can't keep dogs under the restrictions of the apartment. And my GF's allergic to cats... And I want something a little more exciting than a fish. I use to have Anoles when I was younger. If I remember right they were pretty easy to keep alive. Just buy/catch crickets for them to eat and you are all good. This time around I want a Gecko though.
My local pet store has a few kinds, a Marbled, Leopard, and two goldens? Not sure on the last two... Anyways I am interested in the Marbled. Its about 7-8 inches long and looks good. What is needed for getting a tank for him build up? I've been doing some research on tanks and I am gonna say up front I don't want something that looks "cheap"... Sorry if that offends anyone, but I want it to look real, live plants, not the stuff you see in a pet store. Can I do that? From my reading I need to clean the cage often? What can be used for the "bedding" dirt? Rocks, sand, mulch? What's the best heat source?
And about the conditions... How do I regulate the humidity and temperature. Let alone check the humidity?
Then about feeding, how many, and how often does a Gecko eat crickets? Are they relatively easy to take care of? Say I leave for a weekend trip. Will they be fine?
Thanks for EVERYTHING people, I know thats a lot to ask. But I really appreciate it!
