My LA isn't an HQ but a couple of years ago I purchased the HQ VersaTool at a quilt show. I LOVE it. It has etched lines for SID, a curve, a scallop, 90degree angle and notches for your hopping foot to use when going around applique. It really is a versatile little ruler (about 8in long and 4 in wide) and quite inexpensive. I'm sure I paid less than $15 for it. The dealer was actually demonstrating it on a sit-down machine so it can be used on both sit-down and LA. I really use this ruler a lot. Probably one of my best purchases.
