I've thought about the WFT. I only need to trim for 6.5 CM and that's it, so I don't really "need" a solution catered to multiple calibers like the Trim It 2.
I just figured out the issues with my Hornady tonight. I thought it was the lock nut that was coming loose, but it turns out that it was the spindle lock knob that wasn't holding tight. I tightened it with vice grips and it held tight after that for about 30 pieces of brass, which is much better than it's done up til now.
I don't mind doing a chamfer/debur afterwards. I don't shoot enough to justify anything just because it's faster. So the WFT might be a better option. The Trim It II, even used, is about double the price of the WFT new when you count all the caliber dies that come with this one.
