K's Creation Perfect Tension Bars?

[Stitch]

So I have a really nice floor stand with a scroll frame that I do my projects on, and it works well. I don't like to leave my fabric taut overnight, so when I'm not working on something I loosen it. But when working on a really wide project, like my HAEDs, it's a real pain (literally) to tighten it up again and get my tension back. Then, more times than not, I discover my scroll bars are crooked and I have to start over. So I'm trying to find an easier solution.

I have heard about the Millenium frame, and it looks amazing as far as putting it together goes. Unfortunately it's expensive and hard to get in the US. I did find something by K's Creation that looks like it might work, and I was just wondering if anyone here has experience with them.

Here's what I was looking at:

Do they work as they say? Is it easier to get even tension on wide projects with these? Or, is there another solution that's cheaper and easier to get?
