Thought I'd give you guys a heads up. After looking all over for the filters for my quick, I finally gave up and called BOP and asked them where is the best place to find filters, plugs, etc. I was told right here!!! For $42.45, shipped to my home, you get all you need all filters, plugs, stabil, oil. Seems like a good deal to me after seeing some of the prices I found for the air filter by its self. Once again they answered the phone on the first ring, talked to someone who spoke english, and they were polite and helpful, enough said! By far one of the best companies I have ever worked with. You would think after some of my posts about BOP that I'm a paid spokesman. I'm definitely not, I just believe in supporting American owned and operated companies that treat people as well as BOP. I just hope that they don't get too big and forget the little guys.
