I was unsure as to which model dust collector to get.  They all have the same price in their category, similar specs.  Only the paint color and motor seem to be different between models.  Ultimately what sold me on this one, was the Delta brand name and the 5 micron bag.  Upon delivery (free to my door) setup was a bit involved but nothing a big kid wouldn't enjoy putting together in an evening.  Peformance is good, not as powerful as I expected, but I'm using a second stage dust collection separator.  I do recommned that as it keeps the main dust collector bag clean of large debris.  Also it benefits if you suck up bolts or pieces of wood.  There is no protection to the fan blades on the DC.  So having a second stage could save you from repairs later.
