Let the hive mind of Engadget get that for you.
"What is the best wireless surround sound speaker solution? I have a home theater where running wires is just not feasible. I have my own speakers, so I don't want a system that has speakers with integrated wireless. I've done a far amount of research and have only come across a few companies that even offer a reasonable solution: KEF, Kenwood and Rocketfish. Is there anything else out there? What do you recommend? Thank you!"
I still don't get the whole $30 pricetag. You need a PC to run this, so why not just connect said PC via DVI-HDMI cable and a toslink for audio and be done. $10 worth of cables and bob's your uncle. Then you can surf the interwebs with a nice wireless keyboard and mouse.
If you give up Netflix you can even use a Mac with a bluetooth KB & Mouse.
Said PC is someones desktop PC in a different room 99% of the time. Moving it next to the TV would be very inconvenient unless you bought a HTPC specifically for it instead. At which point $30 starts to look like a better solution because then you don't have to putz around and buy a second machine.
But hey, if you are fine with lugging around your desktop all over your house every time you want to stream Netflix on your TV, more power to you.
