Red Snappers, my Quilttak, and the HQ versatool are my go to things.

I found the Red Snapper edge pieces way too hard to use. Instead I made my own side leaders with ticking folded over 2 paint stirs. I can pin on the sides to the leaders and then clamp the 2 paint sticks [one on top of the other]to the machine.

I have the centering tape but since my new leaders are now with measurements I don't use the tape anymore.
