250$ is not a joke and most the newbie here main goal is to earn on airdrop or bounty so there's no way they will risk huge money for a mere script.
Apart from the newbies and posters, there are many rich gamblers and other people who visit the forum. 250$ may be a big money for some people, but for the investors it is nothing. Some may even take a risk to see what this script is all about. So don't under estimate the purchasing power of the readers of bitcointalk.
Anyways, after seeing so many negative reviews, i hope no one buys this script.
