Roger, send me that guys name, I have some real dogs I'd like to unload. ;-) (yes just kidding)
Most of the time, I just like an example of a chip in my collection. I don't keep searching for one in better condition to upgrade. (that's what coins collectors do quite often) But if given the choice of five at a show, I'll try and pick the one that appeals to me the most, for my collection.

Another good example or how non-grading works is the deals I see most often (at coin shows) any chip in this box 150% over face. So a $1 is $1.50, 2.50 is $3.75, a $5 is $7.50, and I won't go near a $25 for $37.50... but it works, it's easy and it doesn't take a grading book, t-square, and magnifying glasses to see that I'll pick what I want and be off smiling.
