I've got a HUO MM, it'd take some serious coin to dislodge that. Probably $20k+.
Tron LE I'd flog for 15k.
I'd only sell Eclipse if I flogged all my system 80s together, so that would make it expensive
Anything else would be out the door for 20% over the odds, even if it is a keeper. Can always get another one unless it is rare.
