Nothing beats a rock solid, stable Mount that can be infinitely adjusted on every axis, then locked down so it "never" moves.
Cheaper mounts that offer one screw on each side are at least better than "One Point Gimbal" mounts that use a Ball w/Set screw. Avoid those like the Plague they are.
The "$135.00" Chief RPA-168 has "Three Screws" on each of the four sides, is extremely low profile, built like a small Tank, and uses a 1.5" Threaded Opening to accept metal or PVC Drop Pipes of wholly selectable lengths.
The "cheaper" 4-point / 4 screw Mounts, mostly have a square Drop that is either fixed or limited in length. Most incorporate a "Spider" design that extends leg channels out from a central Hub to the mounting holes. The RPA-168 comes with a Stamped Plate dedicated to the 8350's mounting configuration. It's the "BomB".
It's really a simple "Ante-up or make do as best as..." kinda proposition. If you know what to look for....you can get lucky though. The two recently shown can work out if you nail the adjustment the first time out....it's just that they don't suffer repeated adjustments very well. I realize $50.00 sounds like a lot less...and is a lot less than $135.00, but if functionality, ease of installation, and good looks count ar all, count no further than 168
Get the Chief through Projector People. Ext 2002 (Kirk) he'll see to it you get it for the lowest possible price. Ask for the Mississippi Special.
