Most people want this item for the skin (as far as I know), so mods doesn't really matter. I sold a q9 with crappy mods for 100k+30e, 2/3 days ago... To give an indication.
100k+10-20. I traded a Q9 Tac + 20k for an unded White Rabbit a few days ago, but that's probably because the other guy was an idiot (I'd also bought the shield for 100k a day before that)
