IO port racing or CDOC

Hey Gang. Sold my home built dwarf and left the my helmet blower in it. Looking for max volume as I'm old and way out of shape. Not fat just not in peak condition. Anyway i want to by a new unit instead of cobbing together on out of a brake blower and a soda bottle with a dish washer hose.... it worked

Both IO port and CDOC have Cool Shirt brand with 235cfm units for $119.

I recall IO Port was / is a GRM advertiser never heard of CDOC before but did call and Know i know who they are.

So who's an active supporter?

Anyone got discount codes for either place or know of a better deal?

Why don't we have a link over to the left to a list / index of advertisers?

anyone use either place?

I prefer CDOC, but only because I have never purchased from I/O.

IIRC CDOC WAS a GRM supporter, I was surprised to not see them in the recent issues when I went back and looked.

IO Port is my preference. Ken is a racer and knows what's important and what's just intrawebs hype.
