Hi, I have one of Brooks', and saw the Renner jig last May. There's no comparison. Check the archives, I think there's a third tool that was mentioned last year. I just retired the Brooks thing, after giving up on clamping a not-included x-y vise in place a while ago, rather to calculate and mark moldings and use the held-upright-but-not-clamped jig simply to hold them (with a couple rubber bands, too). I bought a cheap ($20) angle vise with (sloppy but shimmable) dovetailed ways instead of the Wilton style and which is better suited for my sort of freehanded method - clamping, much sturdier and with a lower center of gravity.
