Styling wise, those look fantastic and will draw customers. Is $50 too expensive? No - it is a new camera that you can buy at a retail store and/or Amazon etc with zero effort, instead of hunting down a used camera and dealing with all those issues. Remember this is targeted at newbies. I have seen plenty ripped off by unscrupulous sellers pawning off broken cameras to them in the past.
In that one recent thread where that kid just jumped in to complain about film prices, then disappeared, I mentioned, as I often do, the best way to deal with it is to shoot half frame if you are doing this 'just for fun'. This new camera directly aims at that, which is excellent because it will keep part-time hobbyists using film, instead of leaving due to cost.
For $20 I bought a new Agat 18K which tiny and fun to use, plus you can adjust the exposure and focus. But I would not really recommend it to a novice as it is very fiddly to use, very fiddly to load the film, you need to have a basic understanding of film speed and exposure, and the VF is pretty crappy with indistinct frame lines. But it can make some sweet pics!
