Ask HN: Any non-Google hardware search appliances?

Hi. Does a hardware box (or software package) exist that is basically a custom webcrawler with an idiot proof UI? I would like to crawl certain topic specific websites and have our magic box spit out an XML doc (or some other doc) with an accommodating html/css piece of code that I can add to my website to call this information via a search field. Hence creating my own custom vertical search engine (without ads). Google has one for $3,000 that they will let you use for two years with a 50,000 page (not site) index limit but it seems like somebody would have made something cheaper that can be used indefinitely . If this doesn't exist maybe it can be a ycombinator entrepreneurial adventure for someone. Anyway, I'd be more than happy to slap down $500-$1000 for it.
