Cadey XPOWER-S Cycling Power Meter is the cheapest spider based power meter on the market today coming in at US$299. This power meter was put up against the Lama Lab Test indoors and Lama Leg Test outdoors with progressively better results after a number of firmware updates were released addressing some issues I encountered. It was a journey getting it to match my other known/trusted power meters.
