In my opinion this is a really nice snake - but I am biased I like all the phases equal - but I do prefer the many differnt varieties of the alterna-morphs. ten years ago I would have paid $200.00 for a yearling female like her that is feeding well. In todays market I think that it is accurate to say that you would be hard pressed to sell her for more than $100.00 shipped.
My advice would be that for a healty feeding lone female try not to go lower than that unless you must, here is why - In my opinion once a hatchling eats it more than doubbles the price, so if the snake is worth $35-$40 as a hatchling (which a non locality alterna is pretty much these days)as soon as it feeds on uncented on it's own it is worth $75, no less - but unfortunately you won't get much more - or at least not enough to worry about. and another year won't really add much to the price either - it will cost you more to feed it than it will increase in dollar value.
If you got to sell her you should be able to. just try to find her a good home and someone who will take good care of her.
and for looks - Wide orange is the prefered by most - (not me) but the best pair for a beginner is a blairs phase and alterna phase anyway, and it is easy to find a nice - lone blairs male.
Locality alterna are an entirely different deal, but overall they are priced pretty low too.
actually if you add it up - between buying, feeding, the cost of the ad and shipping and your time at 75 bucks you are really giving the snake away
Good luck,
