cec tl-5 oem usa version

From the inside view of tl-5, voltage conversion can be done by jumper setting.

thank you for that info on the jumper settings . I emailed the seller for  the  cec tl-5 player but he has not got back to me yet if it is still for sale . there was some info I read that if you want the usa version it must bought from somebody in Canada . I see these units all over ebay for sale so if all you have to do is make a jump  switch it should be the same unit . why some reviews say there are gray units out there ?I found out where to buy the jays audio online which is better than buying on ebay, but they are twice the price of the cec tl-5 players . so is it twice as good, with  these days the home demo is not possible ? 

also is there any usa or Canada  dealers for the cec transports?

thanks I will .
