After reading the thread it struck me that there was no mention of what I think is the most optimized solution for a budget that includes the Smart. There was no mention of the Dust Cobra. Within the general budget range of the Oneida Smart cyclones one can get an equavalent HP cyclone and a Dust Cobra. The Dust Cobra makes an extremely good total shop vacuum with a much higher CFM than a shop vac or premium dust extractor along with being true HEPA and using a "quiet" induction motor. The negative compared to a Smart system is two sets of piping. While not as cheap as a shop vac (only slightly more than a Festool CT) it is a much better extractor for small port machines, including overarm TS guards (unless you have a 4" port). The combination of a 5hp cyclone and a Dust Cobra seems to be the best small shop solution if you have the money and if one is considering the Smart from Oneida then they do. While the Dust Cobra's 70" of water doesn't match the best vacuums very high SPs are not needed for DC but the much higher CFM of the Dust Cobra is. I know a lot of people balk at the price of the Dust Cobra but if you are willing to spend Smart money then it shouldn't be an issue coupled with an "standard" Oneida or Clearvue cyclone the money is still very comparable.
Of all the laws Brandolini's may be the most universally true.
Deep thought for the day:
Your bandsaw weighs more when you leave the spring compressed instead of relieving the tension.
