You might want to consider a pocket camcorder then - Kodak, Sony, Flip (super cheap right now as their parent company folded that part of the business), etc.
Or even a point & shoot digital camera with HD video recording. For the price, the quality is surprisingly good on these little cameras. If you won't be doing any editing and don't require extra features, I don't see the need to spend $600 on a camera.
