John,
I agree to your statement. Need to compare it more to car dealers versus cable companies.
Local mom and pop auction companies are like your gas station style car lots. Small... do a good job and deal on lower end stuff. Every now and then they stumble across something good.
Dealer ships are more into where Matthews and Morphy are at.
Both sell cars... one is just more specialized and deals in better stuff. Morphy like a car dealer ship has a real nice building, friendly staff... you get the picture.
Bottom line is where does one want to spend his or her money?
