Looking For Suggestions re: Wireless Mirroring

Hi Vergens. Any suggestions on a good option for mirroring a PC Display (From a Non-WiDi, Intel Atom Windows 7 ExoPC)onto a television for video/browser playback? Basically, I'd like everything that is on the computer screen, including audio, to play from the TV, while being pushed from the Computer. I have found a piece of software (AirParrot?) that allows you to do this from an AppleTV (even via PC), and I also saw a device from NetGear Push2TV (but ONLY model PTVU1000) which may also do the same thing. Are these my only two, and least expensive, options? Do I have better options (since I don't have WiDi)? Thanks for your suggestions. . . . . . and...begin.
