And trust your feeling, Lor. Visit stores if you decided to sell to some. And chose who you sell to. When I bought my vents, the breeder (associated with Understory Enterprises), would not sell them to me until he knew I had a viable fruit flies culture and he saw pictures of my viv. And for me, it showed how serious he was about his frogs. It might sound harsh to some, but for me, it made me trust him more.
