Remember: Answer the questions as honestly as you can!
Cameras come in all shapes and sizes and you definitely don't want to be lugging around anything bigger than you have to. On the other hand, larger cameras allow for more features, better lenses and ultimately superior images. Serious professionals use full frame DSLRs like the Canon EOS 5D or the Nikon D4s can weigh 4-5lbs with a standard lens attached.
More expensive doesn't always mean better - it's all about getting the camera that suits your needs best. Still, it helps to narrow down your options by setting a budget and sticking to it.
