Ive got a semi polished teal dp fusion fx that is in excellent mechanical and cosmetic condition and has a few upgraded parts and also has the old stock parts and may look to trade in for a new marker perhaps the fusion elite. I dont really have much knowlege yet on marker values over time and all and need to know if its worth selling or trading for a newer gun. Though this gun is absolutely beautiful and shoots flawlessly given it also has a stck oled board. Any help would be great!!
