In case you've got your heart set on the the African Clawed Gecko - Holodactylus afrcianus - picturedi in your link, it's actually showing a Stenodactylus species (not sure which, I'm not good at ID'ing them).
Holodactylus aren't cheap and easy, they're cheap and tricky until they're settled in. Breeding isn't easy either, check some of the threads in this forum to see what's involved.
One thing to remember - cheap and easy isn't always a good combination. You will likely have trouble selling offrspring. The local market will be flooded in no time, you'll have to look into shipping, which could be a pain to do.
