I have a kit with three Arri 650 Plus with an Arri case (the one without wheels), with two Photoflex softboxes, two Chimera speed rings. All of the lights have stands. I spent over $2000 for the whole kit around three years ago. I bought new from B&H, so I'm the original owner. I'm a hobbiest-lighting wise-and these have seen very little use. I haven't even needed to change a single bulb. One of the lights has a scratch on it. I think the mount from another light rubbed it when it was packed up one time.
I am not actively trying to sell them, but I have considered it, because I kind of want a new DSLR. Let me know what you'd be willing to pay. They're located in Brooklyn, NY. Shipping is doable, but it won't be cheap. Factor that into your offer.
