my $ 0.02
Ber = 18
Tal's ammy = mostly 1 (takes forver to find someone willing to pay 2).
Cats eye = 1
Titans/tucs = 2:1
Gul/Vex = as low as 2
40/15 ias or max = around 16
Shaeffer = 8
Unid ss = 8-9
Doomy = mostly 3 unless really good %
Raven = chips unless 20 dex. 19 dex if the buyer is super desperate, but unlikely seeing how raven are not that hard to find for 1 soj.
Highlord = 1-2, hard to sell for 2 cuz I seem to find all the cheap bastards that don't have 2 sojs to rub together
c-ring = 40 sol?

Not typo. I actually saw it on the channel, someone wanted 40 sol runes for his c ring, not 40 sojs! But sadly I only had 16 sol. But ya, c-ring is probably worth more than 40 sol, but just thought I would add it in here to give you folks a good laugh.
Trangs belt or helm = 1-2, and same as previous.

PS. Good endeaver. But a Price Guide is kinda a high maintenance project. Thus more props to you folks.
