Hi Jena, Difference will be felt in the amount of force required to
roll out the metal. I have a Durston mill without the gear
reduction. You need the strength of Samson to roll out sheet and
have to do so in very small increments. I have also used a machine
with gear reduction at the community college - much easier!.
I was in touch with Durston in the UK to see if my machine could be
retrofit with a gear reduction system. They quoted me 135 pounds
sterling (or approx. $224 USD).
I'd recommend you invest in the extra $100 now.
