If you haven't heard about the Kingjoy VT-3510 Video Head, it's a damn close version of Manfrotto's popular 701HDV (now discontinued). So much that the pan handles are interchangeable between the two heads, but of course the best part is that the Kingjoy is VT-3510 is compatible with Manfrotto's 501PL QR plate. Here's a closer look at this video head in the video below.
While this head may not be as smooth as the original 701HDV, the build is sturdy and perfect for tripods that are often set aside for a static angle, mounted to the end of a jib, used on a skater dolly, or even placed on a slider. All while still offering the compatibility of a Manfrotto 501PL plate.
You'll typically find the Kingjoy VT-315 for over $100 dollars or sometimes listed as a Kenro Video Head (as seen here). The big news here is that the one I received was from a listing for JUST $55 Dollars + FREE Shipping. There's only just a couple left, and I think it's safe to say that after this blog post it will sell out quick. Most likely they won't be available for this $55 Dollar Price again (find it here).

If that item has completely sold out, here's an eBay link to more VT-3510 Video Heads, though I don't think you'll find quite the deal I got.
