I tend to go for quality -- especially when I discover the difference from 'economy'. Non-LQS fabrics can be see through, rough, flawed, etc. Thread can be linty, old (I do a snap test and find out if it breaks easily), and subject to tangling (I like Aurifil or King Tut as they save time and work so well in my machine or by hand). Sewing machine (first, a Kenmore) had limited conveniences and getting it serviced took a month at the Sears appliance shop with 2 return trips. My BabyLock replaced it and I've never had a problem (nor used the Kenmore since). I've used other rotary cutters but like the Olfa best. Cheap scissors are for paper only. Even a good seam ripper with an ergonomic design makes a difference. I'm a believer in 'you get what you pay for' and getting it right the first time will pay for itself in the long run.
