I have older 3 switch sockets & remote control from "REV" (written on them) and was kind of hoping that they will work, but

Now I'm searching cheapest Tellstick compatible solution - I guess Conrad is the way to go in my country...
But Conrad has various offers :
http://www.conrad.com/4-part-radio-swit ... 00_0806012
or
http://www.conrad.com/FUNKSCHALTER--UND ... 31_2805011
or
http://www.conrad.com/Plug-%26-Play-Rad ... 00_0806012
Do you have exact list of supported products from Conrad? What is the cheapest compatible solution available on Ebay ?
Thanks in advance,
regards,
Bulek.
