where can I find a ZEX switch, are they cheap and are their immatation ones that I can buy?

 

there is some guy selling them on eBay, offered to sell me them @ like $20 each for as many as I wanted. Said they were made by the company that makes them for Zex.... I'll probably be getting 4 from him soon unless someone else knows of a better price. Thanks

 

i have one that i'm not using...i'll let it go cheap
