How to greatly appreciate AudiogoN....

How to greatly appreciate Rennlist- just go to any parking lot. How to greatly appreciate WatchUSeek- just look at any wrist. How to greatly appreciate Fine Woodworking- just look at any shop (if you even can find someone who has a shop!). How to greatly appreciate Sky and Telescope- well never mind. Hardly anyone has a shop. No one has a telescope. How to appreciate TireRack.com- look at the tires on those cars in the parking lot. Look how many have mismatched tires. How many even know what I’m talking about???

but perhaps that is true for most catagories of consumer products

"Most"? All.

Quality is, has, and always will be a niche market.

The big difference in just random wandering around in the parking lot looking down on somebody’s iron is asking the essential question: what is your fastest lap at Willow?

But the essence of your question lies in the definition of esoteric 

the issue with “ small number” is that it is undefined.

the law of large numbers make FEW actually a decent sized population....

I own a Cellestion Telescope which I love to use in the Summertime.  It's a fascinating universe that we live in.
