difficulty

Hey Everyone, So I'm deciding between two snakes to have as a pet/display for my house. They're both diurnal and usually seen very active around the cage as far as I've been told. I'm deciding either between a snake from the pithiophis genus (gopher, bull, pine) or a Vietnamese blue beauty...

i was lookin at getting some viper geckos and it would be my first lizard so are they hard to look after also there quite expensive setup does any one no were to get an exo terra glass terrerium cheap and what size would be best (i was thinking of gettin 3 geckos) o and were can i get the viper...
