I know what you're trying to say, you want the most for what you can afford. I understand that. If you mention "worth" concerning your reptiles on a forum such as this, people are going to jump down your throat. For $300, the only thing you're going to be able to get that's breeding size is a normal female and a Pastel male. For $500, you could do normal female and male Bumblebee if you can find one for cheap. You don't want cheap though, because cheap is average. Average bred with average produces...well...average. If you're truly interested in the hobby as a hobby and not a means of income, invest in quality animals. You'll never really make your money back, but if you're doing it for the love of the animals it won't matter.I say, just save up your money. Buy several female and a couple of male morphs as babies that you want to breed eventually. Pastel, Lesser, Spider, Mojave, Het Pied and Het Albino are all good choices.
