Some of you guys have a lot more access to old iron than the rest of us. When I needed a new vice I hunted for quite awhile and only came across one that was far from a stellar deal. I got lucky and had a GJ member offer me a non-vintage Yost for a good price, but I had to get it delivered from Houston.
Re-read what I wrote - I thought I was pretty clear. The OP asked about Tekton, I told him what little I knew about them. When I was hunting it was presented as a possible option to consider, mostly because it was a CHEAP and temporary alternative. To be clear, I'm not arguing they're comparable quality to vintage American iron, not by a long shot. But if I needed a vise NOW and had the choice between a Tekton and the vintage vise I can't find at all, I'd go Tekton...
Compare Tekton to HF if you want, but HF doesn't lifetime warranty their vices so even if they are identical in every other way (ignoring shipping, coupons, etc) you can't walk into HF and get a new one when it breaks - and the point of this is that we all know it will.
