Congrats on the pickup! The OOW M240 looks great on top of any coffee table so that's definitely a pro. Some may balk at the idea of paying $14k for a semi belt fed, but the platform is so stable you can stay on target pretty easily while laying down a string of shots with unending capacity. I wanted something different, always been fascinated by belt feds, and I've added 2 other platforms since. They seem to retain their value pretty well so while I don't personally buy guns as investments, it's easier to justify such a purchase knowing you aren't tossing your money away. Mine's been reliable as well so that's a plus. Only con is it's a heavy beast to lug around but it is what it is.
I have one of those Predator Pack setups for it too, something about those feed chutes aha but have yet to try it out.
