I just purchased a 2012 Firefly female for $850, shipped but with the ones you're looking at being a younger pair, you'd have quite a while before they would be breeding age and you could make any of your investment back. Were it me, I'd go with the second package (Mojave Orange Ghosts). You'll have no problems recouping your investment on that deal with your two breeder females and with the younger two, you could hang onto them or sell them off. I love my Firefly that I just bought but if my wife and my bank balance would allow for it, I'd absolutely add some hypo to the vanilla mojave male I have. Recessives are more work but if you have a visual male and a few het females, you're upping your odds considerably. That, and hypo mojaves are H-O-T!, lol! Ultimately it comes down to what you like; if you're just doing it for the money, I wouldn't plan on it holding your interest or being a long-term thing if they don't prove out. Pick what you like and go for it. Good luck, whatever you decide.
