What is this worth?

I have a pretty used 998c si, it has a chip in the screen, both the high speed and the si transducers with the splitter included, plus the big ram 111d mount. Any idea what a fair price would to ask for this? The chip does not go through the screen and it’s nearly $500 to replace so I’d like to sell it as is. Once I have an idea on the price I will post in the classifieds, won’t sell here.

I’ve seen good condition 998’s selling for around $500, I’d knock another good chunk off if the screen is damaged…add about $50 for the ram mount… With the Helix introduction and the big box stores clearancing the 9 series legacy units, it tough to sell 2-3 year old units right now…
