I have a pair of 100% axanthic hets. I plan to give the female another year since this coming year would be pushing it, but breed the male this coming season to get poss. hets. But the kick is there is a way to pick out the ones that are probably the hets. At least with the SK line, hets when hatched have a green tint. They also have 'markers' [more like tell-tale signs] of being hets. It's not the fastest way to do it, but probably the cheapest.
I only paid $500 for my pair as babies at a show, most of that being the female. You should be able to find a male het baby or juvie for $200 shipped, a proven breeder maybe only $400 shipped.
Axanthics are key to many other morphs, and many more to come. although the price will slowly drop, I believe they will always hold a fairly good price.

Hope this helps
