I started on a Delta like the one you described, I wish Blacksmith forum was around then, it worked for very lite duty things, but beyond that is was useless. The small design really limits the potential you have in your head. Not to mention the belts wear out in the blink of an eye, when they are that small. Good Luck in your quest, I agree with Thomas about building one, with little resources and some time you can build a much better grinder, than those for sale a home improvement stores. Matt.
