I have a rcbs branded one and a dillon one.
The rcbs one I use for wet pin tumbling because it has a lid,
The dillon is used for walnut media
Pros
Rcbs :cost, covered lid
Dillon: heavy construction, pin that holds basket from turnng when loading, well designed and built hinges and latch.
Cons:
Dillon :cost, open top (I don't turn it fast, so it is a non issue to me) large footprint on bench.
Rcbs : 2 peice basket and handle, hinges and latch,
I won't go back to a collander or sift pan.
The dillon gets used the most.
