RIA estimation is not always high. This pair, $900 - $1400, I put down a number, say, $1400, adding 15% is $1610, adding shipping, assume that's $1700. But will they come at $1700?? most likely, no

But put down $1400 there, if no win, cost me nothing anyway.

If they do go under $1400, the dollars saved can cover the cost of my book "Parabllum's back"

Probably that's day dreaming. But no try, no win.
