I have 3 of each edition. I keep one of ea in my truck & near the PC. With the price of one on Amazon, maybe I should entertain offers! LOL
I vote for no pricing [everyone can add their own w/ little postie notes or pencil in].
10 guys across the country can't accurately est. the Correct value of every pump ID'd, let alone all the extras that might be included in 3rd edition.
Just as soon as a pump is given a rarity of 9-10, w/i a year 3-4 will show-up on ebay for sale @ 2-3X the est book value.

DO IT, I need 3.
