If you see this ad. you know what you're looking at. Everything works perfectly, all tested. No issues, these items are completely original and don't need any service done. All four items on eBay are over $1600 if you buy them separately. Now I'm selling them as a combo at half the price because I don't have the room. If you have any questions feel free to ask me. These are heavy units so they are nice and strong.
Attached as all the sold and completed eBay items. All of them separately is $400+ each.
