I just recently received the new Rode VideoMic GO. A very straightforward, no fuss, directional microphone under $100 dollars (found here) for your video camera. No batteries required, and will improve audio capture over using the internal microphone from the camera, and of course with an extension cable you can use this off-camera positioning this closer to your subject.

Rode VideoMic GO Overview
The VideoMic GO On-Camera Shotgun Microphone from Rode is a lightweight microphone which adds high-quality audio recording to your small camcorder and HDSLR camera. At only 2.6 ounces, the microphone keeps your camera setup lightweight, making it ideal for handheld shooting. It features an integrated Rycote Lyre shock mount for isolation from bumps and vibration, and offers battery-free operation, using instead the plug-in power from your camera's 3.5mm microphone input. Please note that the microphone will not work with cameras that don't supply plug-in power to their 3.5mm audio input jack.

The VideoMic GO is a directional microphone. It utilizes a super-cardioid polar pattern to attenuate sounds from the sides, resulting in a signal that sounds closer to the camera, even when shooting in noisy environments or at moderate distances. The integrated shoe mount provides a 3/8" thread for additional mounting options. A foam windshield and 7.9" dual mono 3.5mm coiled output cable.

Now i'm a big fan of the sound quality from a Rode VideoMic Pro (seen here). If you can hold off and save up, the Rode VideoMic Pro is a solid microphone to have in the kit.

Realizing that we all have to start somewhere, the new VideoMic GO will offer you better sound capture options than working from your in-camera microphone, and this mic comes pre-built on the Rycote Lyre Suspension System (no rubber bands to wear out). Check it out at B&H (click here).
