If you're looking for a folding camera that will allow you to simply wind on to the next frame without having to align the number in the red window (which by the way is near to impossible at night, having tried it last summer), then your best best is a Super Ikonta B.
To further elaborate, a 531/16 uses separate windows for focusing and composing. Not the best choice.
The 532/16 can be found with either a coated or uncoated Tessar.
The 533/16 includes a selenium meter (often not working).
The 531/16 and 532/16 mechanism causes the loss of one frame. The 533/16 gives you 12 exposures on 120.
All three cameras are somewhat heavy, and you must manually align the first shot. Not that big of a deal.
The Super Ikonta III and IV are lighter cameras with excellent coated f/3.5 75mm Tessar or coated Novar lenses. They also have autoframing mechanisms.
But it's unlikely (not impossible) you'll find any of these cameras for less than $100 -- probably closer to $200. And generally any or all of these cameras will need to be serviced to some degree.
