I believe the Eclipse vises are what is recommended by many here. I’m also in the US and found them to be readily available on Amazon (link below). The 9″ or 10″ would both work well but I think the 7″ would be too small for a front vise. Hope this is helpful. Had to edit the link a bit so it would work so you’ll want to just copy and paste everything between the arrows.
When I bought my eclipse the giant, 10 inch version was substantially cheaper than the 9 inch. I bought the 10 inch. It’s really heavy. It also came with about a 10 degree bend in the handle, so maybe that’s why it was cheap. Anyway, it works great on my 5 foot bench even with the bent handle. Just food for thought.
I got the eclipse on Amazon and I had a defect. I got a replacement and it also had a defect. I was able to swap out the defective part of one for the other (defects were different) and returned the other one. Check your product!
