I use the price of 50 cents per gram as a baseline (seems to be the going rate on pastels) and then look at the other factors that could determine price, so at 600 grams, the base price would be about $300. Then you consider that she's a mouse feeder and that adds no value. She's got nice blushing and pattern, so maybe add $50 more. She's an early 2010 which means she could potentially breed next season if she got up to size, but on mice, that will be harder to do, so you can't really add a ton beyond that.

I'd pay $350 - $400 for this particular girl. If the risk on getting her to size fast enough is a concern, then I'd pass all together and look for another one with better potential. It's all about what you're hoping to gain by adding her to your collection.
