I have proven breeder Spider females that I would be willing to sell for $5000 each. They are just too valuable to sell for less.Just think of what I can make if I brred my Sterling male to a female Spider that produces 10 eggs. However, as others have stated, I would expect to pay at least $1000 from someone that is actually interested in selling one.
p.s. I don't generally rant, but I can't believe the prices I have seen on proven breeder females. The potential to make more than their price from a well selected breeding just makes it seem like a bad business decision sometimes.
