Ace, the wallmart cheapies as JV has called them are regent 30-60's I believe. correct me if I'm wrong. If you buy a penguin 330 bio wheelsetup (not the filter, just the wheels and holder and top) then they it would be a penguin 330. regent and penguin are the same thing as far as motor and chassis go. the only difference is the addition of clip in bio-wheels on the penguins. I converted a Regent 5-15 into a penguin mini!!!
