What the winner pays, is one of two possibilities. What it is worth to him, or what comparable local items run; then cost to reel it in.
Have to decide what you'll look for, the max dollar amount, and plans to retrieve. Auctions are OK, but you never know who competition is. Bid small to open and hold off until it slows down then throw your max at it. You'll win or loose, that part doesn't cost a dime, and experience unobtainable.
I needed decking for mezzanines. Searched out materials regularly. A hugely advertised industrial re-use site had standard metal grating that worked out to about $2800.00, ~$5.40 psf, for 528 sq. ft.
Diligence paid off, found fiberglass decking, also used but full size 4'x12's. 1776 sq. ft. worth for
3 decks, 12'x44', and two of 12'x24' $1600.00. So, was a pleasant roundtrip to Central PA worth it?
Been looking for a 'compact' radial drill. Almost won a Wells-Index Model 125 until it passed value boundary. Nice design, I'm familiar with them, waist high table, step pulley, radial function swivels the 4" column, ram is on rollers. It's just a Bridgeport head in #3MT, a serious limitation in my book, around 4-500 miles away.
Found a Veet instead!
7hp, #4MT, trigger-eject spindle, 6" column still supported by company that also stocks
Axelson lathe parts. Won for less than 1/2 that of the Wells, and gladly head to NJ for it.
Can go awhile on compact radials; #1 Donau, #Oerlikon, #Veet, #American TW, #4 Morris, Carlton, they are scarce. There are good Euro and Japanese radials.
Don't waste money rounding up a Johansen. Popular being a lot around, so people know them, that jacks price up, but the elevating table slides on a grossly narrow Vee way, not stable at all. What good is 3' of range if corners deflect?
It came with a handy vise......
