Pay 'em no mind. Price police pop up all the time. Once I put a machine at a high price. Sure enough out they came. Sold in two days though. Buyer didn't even haggle. Shows what they knew.
Friendly advice to help you sell; get some more light on the machine and take higher resolution pics with the glass off. Add pics of the boards and inside the cabinet. Us pinheads can be picky as you see. HUO means never been routed. You probably just meant HUO since you got it in 2004. GLWS!
