If your thinking of hets I would recommend female possible hets.. they are alot cheaper than 100% hets, basically for the price of one 100% female you can buy a whole clutch of 66% and you know for sure at least one or two will be hets.. the secret is trying to buy an entire clutch..

I am in the process of buying 1x100% proven breeder het pied male, 4x66% het females and 4x50% females all within your budget, heck i could get the heat tape and rack built within your budget too... I figure at least 3 will turn out hets with a chance at 4-5 being hets. and if they dont prove out I can sell them as normals for more than I paid anyhow.

Good luck! There are so many options!
