Is there a "go-to" resource, magazine or website that restaurant owners use to buy equipment, and get advice?

We've not found a silver bullet in this regard. We did attend the NRA Conference in Chicago a few years back and got some contacts for specific items. We bought/sold things through word of mouth locally, and I think some of the industry mags can help. 

restaurants equipment supplies like Central Restaurant Products they have many advisors 

If it’s out there as one single thing like a particular magazine for advertising and acquiring equipment... I don’t know about it. Atlas on coliseum for eq
and social media for advertising is what I do.

not in particular 

I usually look for everything online using key words. I am not sure if people look at print anymore.
