Anyone know of a freeware OPC trend tool?

Hi, We're looking for a freeware tool for pulling in analog values via OPC in real time and presenting them on a screen trend. Googling gives surprisingly few hits, and the couple of apparently free ones we've checked out in fact cost significant $$ when you read the fine print on the website. Does anyone know of something? TIA
