My husband has been wanting a retic for a couple years too and I was very hesitant to get one. I finally bought him one for xmas this year from a reptile show. Boy did I fall in love with them! Just by looking at their eyes you can tell they are thinking and observing what's going on around them. And he is such a well behaved snake. He has a great personality and great feeding response. He is growing a lot faster than the other snakes we have.
We liked retics so much that we're getting 2 dwarves and (fingers crossed) a purple from Harry Wessels. We're also picking up 2 more Boa Master Cages from the Hamburg Show. By this time next year, the 2 regular ones will be ready for 8 foot cages
So my opinion is I think they are great snakes. As long as you are prepared for having a fast growing snake and a freezer full of bunnies. Do you have any other large snakes? Are you looking at dwarves or regular retics?
