I have that one. Its a good base to customize.
I converted mine into a 2 stage with a separator and a trash can. Then swapped the filter for one that filters much finer.
Me and my buddy both had the same issue with dust leaking around where the band holds the plastic bag on. Its fixed by wrapping painter's tape around the top edge of the bag. And since mine is a 2 stage, barely anything makes it into the bag. I'm on 7+ years, still on the original plastic bag, with only a few lb of sawdust in the bottom of it.
