I love my rotary cutter and cutting mat...and I love the creative grid rulers. It did take a while to get till I felt confident in my cutting, but now I don't dread cutting at all. I do prefer Olfa rotary cutters, though I have heard others like other styles but will use the olfa blades in them. I use the big rotary cutter at least 75% of the time. The big blades cost more but they last a lot longer. I have had two different white mats that I do not like...love the green mats by Olfa.
And I love good, thin straight pins.
I LOVE my Juki 98Q for piecing and freemotion quilting...but I think you are meaning the smaller accessories.
