im just using a shopvac and small separator now so the hf is a huge improvement. with the the $179 magazine coupon i can get it for $144. i have one that expires in april and another in june and probably more coming so i have time to stew over it. the wynn filter was what i was thinking of getting til the grizzly was mentioned. have to see about those. the hf is perfect for my shop and my abilities. low quality and cheap. i dont have a planer or a jointer so im not as messy as most of you
