I purchase mine at full price and don't regret it for a minute! I use mine all the time for trimming and squaring up. My sewing area is small and I just don't have the space for my machine, extended sewing table and a cutting mat. Especially if I need to rotate (and I probably have all the Olfa mats in all the sizes which I use as well). So when piecing and building my blocks the smaller rotating one sits on a tv table right beside me and works like a dream for my needs.
