>>3164849>120mm film: 0.80eu per shotIt's just 120, not 120mm.
"120mm film" would be enormous. Like 4x5 but roll film.
120 is a meaningless product number that was given to that film size when it was first introduced, not an actual indication of its size.
>Is there any good TLR you can recommend?Pretty much any (real) TLR should be fine. There are also a bunch of fake TLRs out there that don't actually have the ability to focus using the viewfinder (really just boxy-shaped viewfinder cameras rather than TLRs) or set your exposure settings, and those should be avoided. The Kodak Duaflex is an example of what you should avoid.
>Or a digital that can be modified with a waist level finder and looks innocuous?Digitals with flippy screens can act like they have a WLF (e.g., most Sony mirrorless cameras). You might also want to consider shooting street on your phone, actually--as long as you have the shutter sound muted (and aren't in Japan) and are conscious of how you're looking at your phone, you can take pictures of people and just look like a random yahoo looking at porn on his phone rather than a photographer.
This assumes you've got a phone with a reasonably decent camera, like an iPhone or the higher-end Samsungs.
