They're suspect because I just got an unsolicited spam from them. Some of the scripts, simple as they may be, seem useful enough. However, their pricing and lack of contact info on the website makes me wonder if these are just stolen scripts from some other website. They're selling a package of 5 scripts for just $99 and they have another product that looks cool as hell for allowing one htaccess file to refer to multiple password files.
If nobody thinks these guys are thieves, I just might buy the scripts!
