• I just came on to see if anyone had experience with these too! I know what you mean about the plastic ends on the second one - the cheaper one might actually be more solid in use as it seems you need to adjust & clamp into place for different widths.

    The other one I've been looking at is this from AliExpress - good reviews but £100-120

  • I have one of these. It's fine, seems to work well enough, but it isn't that rigid and the studs which the dial gauges ride on don't have any way of locking, so they sometimes unscrew themselves.
