How we justify what we think about this type of issue fasinates me.
I like my vise. Most folks 'like' the vise they have. Those that do like their vise, whatever it's features and cost, find some reason to offer justification for why they own/like that particular vise. We've seen quite a bit of that in this thread already.
Those that do not 'like' their own vise are probably looking for an upgrade. What they choose to purchase will reflect their perception of their needs, how much they can afford to spend, the effectiveness of advertising, and their reliance, or lack of reliance, on the things they read on sites like this.
Some folks will always be looking for the 'next best thing' in vises, regardless of what they have now.
Fascinating how the human animal deals with something this trivial in the grand scheme of life.
YMMV
