vise for machining multiple parts.

Hey everyone, I'm shopping around for a vise for my cnc mill for machining multiple larger parts (4"×10") and was hoping to get some help finding some different sources.

I'm currently looking at

Homge vise in row
https://machinetoolsolutions.ca/product/vice-in-row/

and
Tombstones comparable Modular vise
https://tombstonecity.com/modular-vises/

I was wondering if these style vises have a specific name I can search for finding more manufacturers or if any of you may know of other manufacturers of these wedge style vises.

Main specs I'm looking for are 2.75-3.00" jaw width and can hold two parts at a max 10" length. Currently have quotes in the $3000cad range and trying to find some potentially cheaper options before I bite the bullet.

Thanks for having a look and your time.
