I go for quality at a good price. I use Olfa blades from Joanne's on sale -- I have several Olfa cutters (all more than 7 years old) and working wonderfully (love the 60mm ergonomic for most jobs and the 18mm for ripping) -- the F&P that I won last year, I use for cutting paper because it does not feel good in my hands. I have a couple pairs of Ginghers, 2 of the microserrated blade scissors and the rest Fiskars because they fit my very sore hands the best.
I try to do quality on a budget -- I find that buying cheap costs too much in the long run because I keep having to replace it.
