I love love love my Bloc Loc rulers. DH surprised me with a set for Christmas. Sometimes that man actually does listen to me!! I have an Olfa rotating mat and wish I had bought the bigger one. It was very handy when I was squaring up disappearing hourglass blocks. I adore my Pffaf 5.0. I know I really didn't 'need' another machine because my Janome 4900 works just fine, but she is my 'go-to' and I miss her terribly when she needs a spa day.
I wish I hadn't spent the bucks on my June Tailor strip cutter. In my opinion it is flimsy and I almost cut right thru the end on my first use. Just not user friendly.
