I have recently "upgraded" to the Martelli rotary cutter and the Martelli cutting mat and would highly recommend both. They are pricey so register at their site and wait for their sales to purchase. I also would not be without the SlideLocks now that I've learned to use them properly. Deb Tucker's tools are also pricey but worth it. All of these items have increased my accuracy and decreased "oops" moments, frustration, and "do overs". I believe they have paid for themselves when I consider ever-increasing prices for fabric and patterns and the time I've wasted over the years fiddling with stuff to "make do".
