A good PC to TV Wireless Video Sender?

Hi all!

I have a pc connected to my tv (S-vid connection). Since the tv is the CRT type, I still need to use a monitor so I am able to read the text. (blurry on the CRT tv)

I am looking for a solution where I can put my monitor on the coffee table & have a wireless connection between the monitor and the pc. I will still connect wired from the pc to the tv via. the S-vid & audio conenctor, since the pc is sitting next to the tv.

I also need to get a wireless keyboard/mouse setup as well...

Any suggestions for A good PC to TV Wireless Video Sender? Not looking to break the bank here if I can help it. I see prices ranging from $40 up to $250 or more.

Thanks!
