wireless monitor for 5d mark ii
 

Hello there,
I am looking forward to buy an external wirelles monitor that I can use with my 5d. I remember searching the forum last month and i found one monitor that could work at maximum 30feets wireless. On the same monitor there are all the buttons that I can control the DSLR. unfortunatly I forgot the name of the company that produce this. ( the price of this item if I remember well must be is 299-350 usd) can anyone help me to find that company and the monitor?

thanks
