Could you be looking to replace
this Bluetooth transceiver with a cheaper Chinese counterfeit? Good luck with that. The Chinese are really good at reverse-engineering and duplicating successful commercial products, as well as developing some pretty nice technology on their own, now that they have developed the infrastructure to do so. However, companies that make counterfeit parts don't pay any royalties or fees to the original equipment manufacturer, so production costs are very low.
Try visiting the Amp'edRF offices in Tianjin, China to see if they will cut you a deal on large quantities of their original product.
