Sorcerer is starting to get some much deserved attention.
Based on the images and your comments I'd think between $800 and $1000.
If you do buy it I recommend LEDs in the inserts and backglass.
Keep the rest of the GI incandescent. They look best under the plastics.

2 years ago I paid around $1500 for my sorcerer that was fully shopped. Plus it has a NOS CPU board, new pinscore power board, new Rottendog displays, full LEDs and the playfield was touched up and clearcoated by an auto shop.
$1600 sounds high to me but condition is king.
I'd try and get some pics of the boards, backside of the backglass, under the playfield, and some clear photos of the playfield with good lighting so you can really see the condition of the table.

Sorcerer is very tough to find in decent shape so if this one is really in nice shape I'd think $1200 is as high as you would want to go.

So true. So true.
I hope someone (hint hint- CPR) makes a new playfield someday.
