I will say that the Duraforce Silver Series are nice machines, atleast after you do alittle mod to the carb. My grandmother has the 10323 as well. I had to do a mod to the carb to fix that problem of surging that it had. The surge is caused by the jets in the carb getting dirty and leaning out the mix. Good old EPA brew haha. After the mod, the machine runs beautiful. Burns alittle more fuel cause the mix is richer now.
