I have been impressed by the cost & quality of components from china, like others, two weeks delivery seems to be the ballpark.
I have bought some neat little panels having both an FM radio, USB & TF card slot MP3 player, it also has bluetooth, aux input jack, led display and a full remote control
All for about £3.60 inc postage! I intend to fit one to my Bush stereogram, all that is needed is a 5vdc supply.
I have tested it with a spare mobile phone charger, and am very impressed with it's performance
