eBay CheapScript

Occasionally, an item worth $1k+ with a starting bid of <$1 on eBay will not sell, or will sell for this price. This means that someone who had stumbled upon it right before the listing ended with no sale could have bid a dollar and won the item. I'd like a script to do this automatically. I just need a script that will buy me eBay items that have a Buy it Now price of $1k+, but could be won by bidding less than $50 (or another insanely low price, maybe $5).? ## Deliverables Please note that I would not like the item to just buy every applicable item it sees; if it spots 100 items within price range one day, it should not buy them all, just one. In other words, I need it to limit itself to only winning 1 item per day. And yes, this is vaguely inspired my the xkcd strip.
