that's the one i have too.
i got an extra belt, but found out our 4" hose rings at work fit too so i nabbed a package of those.
they didn't have an extra lid gasket when i bought mine or i would have got one of those too.
i already had the Dillon media separator which works really well, but have also used the little frankford arsenal strainer on a 3 gallon bucket with good results too.
one trick i have picked up on is to fill the separator tub with hot water and swish the brass through by rolling the separator through it for both a rinse to the brass and to help the pins release easier.
i have run it with tumbling media to de-lube about 400 223 swaged bullets, or about 100 rifle cases at a time almost as much as i have run it wet.
