Need advice on Leopard Geckos?

I noticed alot of people on here have leos. I am looking into purchasing one. I am new to the whole reptile thing and I heard that leos are great for beginners. I wanted to gather as much information on these little critters as possible. i always go into things whole heartly. I always want to know as much a possible, before I get into something, because pets are something to commit to. Plus I do not know any one who would purchase a pet just to have it die. I have read many care sheets, but I find the best info comes from experienced owners. My eperiences in reptiles include. Caring for 6 Firebelly toads, and caring for a Russian Tortoise...
