I started a new website called MorphMarket, which lets you do super-specific searches on gene combinations, including hets to find out the going rate. Also it includes not only the current for sale but also previously listed data. Over 4,000 data points and growing.
In the future, this data can be used to produce current market price and trends for different morphs.
(I am only mentioning this site on here because it is exactly the topic of this conversation).
