I have known large and small shops with more than one collector eventually move to just one collector. Once they figure in the cost it took to deal with what was collected, they moved away from multiples. One large shop put in about 12 small collectors. The noise alone was enough to make them rethink the decision.
In my own situation, I once had a bag collector, but lusted after a nice central collector - that I thought I could not afford. One day, after changing that d*^m plastic bag on the collector for about the third time, taking it outside and dumping it in the trailer, I sat down and did some math.
I found that the time dealing with the output was adding up to enough time - enough dollars - away from real production that I had already paid for the collector I needed, but I did not have it.
I ordered a new system the next day.
Once you collect the shavings, dust or whatever, you should not have to see or touch or handle it any way, or it detracts from your ability to produce. A collector system is not sexy or cool, but is part of your infrastructure, like a roof. You do not want to actively maintain a roof every day - you want it to just work without your involvement.
