>>4482569You could substitute Rollei 35 but there's nothing like the TC-1 and you pay for it sadly.
I don't know anything about DSLR scanning. I've seen good results. I do know you aren't getting the most out of a 6x6 frame (let alone bigger) by reducing it on a 35mm size sensor without stitching or pixel shift wizardry.
If the 1:1 ratio appeals to you then certainly 6x6 is the way.

>>4482574Some wise words here too, although you can definitely get good results handheld.
