I would lean towards the 8967 but this will require a bit more than the "bolt on and go" that the other two provide. The 8967 is the same style as my (as yet uninstalled) LV vises. The other two have only an 8" opening. Subtract 3" or so for faces and your dog holes would have to be pretty close together. The difference in price is less than a case of beer so I would choose the one you prefer (there is no "right" answer here; too many variables).
If you go with the small QR vise you will at least get to see if QR is really important to you and you can factor that in if and when you go for a larger capacity vise. 70% of my vise work involves bench dogs so as long as the vise has a greater capacity than my hole spacing, I'm good.
Any sufficiently advanced technology is indistinguishable from magic.
