Hi Marvin - I have had the best luck with Circuit Specialist in Arizona. Circuit Specialists Inc. 220 South Country Club Drive #2 Mesa, AZ 85210 Phone: (800) 528-1417 +1-480-464-2485 Fax: +1-480-464-5824 Telephone Hours: 8AM - 6PM MST Arizona Time Monday-Friday contact email - firstname.lastname@example.org
These are the folks that Mike Dory referred me to. I once tried to buy a case from an outfit in New Jersey and it was a nightmare!
Also make SURE you order the refills, not the ones that come equipped with plastic triggers. Those won't work.
The correct item will say "For use with M.G. Chemicals Cat# 402-T Chrome Plated Trigger Valve". THAT is the one to get. You can just click on the link below and go right to the correct page on their ecommerce site.
PS - one more thing - be sure to order early. They don't have a huge stock of this stuff so don't wait a week before a regatta and expect to order a case ($5.15 per can in case lots vs $5.50 ea per single unit) to order!
