We've got some major heroes on board this week, from those serving the country in full honor and glory, to childhood heroes. Marshmallow Men busting ghost agents (Ghostbusters: The Video Game), WWI fliers, they're all in this week's On Shelves list. Dig in and enjoy.

UK-based retail chain Argos is currently offering a PSP FM Transmitter for just 7.49 GBP or roughly around US$ 15.24. Unlike the previous similar gadgets that we've seen before, this one sports a rather sleek design and is smaller in size which seems to fit well with the Sony PSP.

Anyway, here are some of the features that comes with this particular PSP FM Transmitter in case some of you are interested in purchasing one:

• Especially designed for the PSP console, it allows you to listen to the MP3, UMD game, and sound track stored in your PSP console, through any FM radio in your car or home.
• Enjoy the benefits of wireless transmission with sleek design and bright blue LCD display, simply plug the transmitter into your PSP's headphone socket and experience the crystal clear sounds on a radio station where you're in control.
• For ages 8 years and over.
• This product is not compatible with the new PSP slim & Lite.
