It's a sad time, but FYI OSAGE ROOST will be pulling the plug at the end of the month. It's been a great 15 years since the start, but it's hardly ever used now and time to move on!
Sweet looking call John and I hope things get better for you. I use the 3M respirator that can be picked up at Lowe's and have used them for 10 years with great results.
