Hello and welcome! I highly recommend leopard geckos. I have one, and he's my first pet (exotic or otherwise) and I absolutely adore him. My only 'warning' is that if you're looking for a pet to cuddle with and handle a lot, a leopard gecko would not be the pet to get. They tolerate handling, but generally don't like it. I'll put my hands in the tank and if he comes to me, great! But I don't force him to come out of the tank.
Good for you on researching ahead of time! There are a lot of helpful threads on this forum with great suggestions about tank set up, diet, and other resources.
Here's my sweet little Reggie:
