First 4x5, make sure it has light tight bellows as few first timers want to replace a bellows.

I don't recommend a $500 CAD Sinar F1 for anybody.

Whatever you buy will be not what you want in under 2 years. You will buy a different camera and lens.

So buy cheap, but with good bellows, and a cheap lens with good working shutter. Best deals are camera with one lens.
