Here's some Nextag dust collector prices
so half cost between $280 and $450; prices outside this range may be suspect.
I guess you want to maximize hp and minimize noise level and price.
DBs of noise level are meaningless without the measurement distance stated.
You could first compute hp/$ and then look for minimum dBs within this max hp per $ subgroup. The asterisks mark the top three candidates for hp/price.
