Isn't the film and the processing part of the experience? I would have thought so. Maybe I should try using a TLR one day, but every time I pick one up, the mirror image viewfinder scares me to death!
Noob question though, why would you want a digital TLR if you could have a Hasselblad with a waist level finder and digital back?
Not sure why, but when I came across this thread I had this weird image of one of those plastic lomo TLRs.
