Personally, if I was on a tight budget, I would go for two double gene snakes. When I purchased my most recent male Ball Python, I didn't have breeding in mind; I purchased a single gene Mojave. Now that I am looking at it from a breeding viewpoint, it makes more sense for me to have purchased a double gene male, and either a couple single gene females or one double gene female. I would do that if I could start all over, BUT, unfortunately, I get quite attached to an animal once I get it. I do believe in quality over quantity though, therefore if I found a stellar single gene snake, I'd be willing to pay a little more and wait a couple years for some of it's double gene offspring (rather than buy two not-so-stellar double gene snakes). I'm not in it for the $$ though, so I don't see it as "wasted time."
