I've finally bought a HF 40 blast cabinet and come to the realization that my existing compressor won't cut it (craftsman 15 gal, 3.5 cfm @90psi ) .  I'm not getting enough suction to pull the media from the bottom of the cabinet.  THe blast cabinet recommends 9.5 cfm @ 90 psi.  I see most 9.5 cfm compressors getting to the $1k + price.  I was really hoping to spend less than $500, but the best I can get from that price point is about 5-5.5cfm.  Will I get enough pressure/volume from a 5.3 cfm t
