i have scat blast cabinet that i bought in 1994. needs some upgrades i think. looked at you tube on the hf upgrade and tried talked to tacoma co owner. they moved from washington state to utah and can not get an answer on either number. i found another place that is called partswasherupgrade.com and saw some of their videos on you tube also. the price difference is "wow". tacoma is about 700.00 by the time you get their upgrades and the other company is under 300.00. anyone have any other companies they have had good luck with? both kits remove the suction tube and have a pipe in the trap door, along with other mods. tia. rick w.
