Dust collector bags

[Scooby]

Anyone have a source for dust collector bags that are reasonably priced? I have a Dayton 6C503A with a 10.5" opening and having trouble finding bags for it. I can have them made but that gets pricey. Any ideas what I could retrofit and make my own? Thanks

I have seen the heavier trash bags used. I have seen bags emptied and reused. I have also seen them taped up to extend the life of the bags.
