I modified my Harbor Freight 2 hp dust collector by adding a pleated filter and a new flex hose and accessories. This has significantly improved the suction (anecdotally, I didn't take any actual measurements) and should result in much better air quality in my shop.

There is a ton of good information on building a Thein Baffle in the forums on this website: http://www.jpthien.com/
