Like many of you I have the HF 2 HP dust collector. I recently went to HF to pick up some replacement bags and I was told they don't sell them. The largest bag they carry is a 55 gal and the one for the dc is 70 gal I believe. I looked on the internet and didn't readily find any so I though I would see what you folks use . Does anyone have a source for the bags? If not then I assume everyone must be using a drum?
