Seems like I missed the edit deadline. More free advice: Most flippers derive market price by using pre-existing marketplaces data like eBay/Terapeak and Amazon new/used to figure out where the market roughly sits. These venues have strong incentives to regulate listings into consistent item buckets to make sure people can't (CL)SEO listings like CL spammers ("2011 Macbook Pro" vs "2006 Macbook Pro with Office 2011", or the giant paragraph of hot items in small text and white font to catch your search attention). Once you get that magical price point/band, you can pretty much go to town with some basic clustering analysis. [Disclaimer: worked on a few private, weekend projects in this specific niche.]
