If you take some time to sift through the rhac/crested forum you will find that often times "cheap" is not what you want to be looking for often times the cheap geckos are a week or less out of the egg and the breeder wants to move them so he/she doesnt have to feed them or get them through their first delicate weeks of life, I would recommend starting with animals that are around 3-4 months of age that are well started and have good weight take the time and find a good breeder that will take the time to help you in your success it will be worth the little extra
As far as what your getting in to .. they are much more work than snakes certainly but not hard to maintain ,feeding and cleaning are an every day chore that has to be done, they like to pay in their food!
