Dear all, thanks a lot for sharing your experiences. I conclude it is definitely worth a try placing at different places mainly close to the CD player, especially considering the low prices involved. I shall buy some from the online sources you mentioned to play around with them.
Freemand, I could only locate one Hong Kong based source in ebay - did you buy from the same source or was there another one too.
