What's the best budget paper trimmer?

In this pool, the Firbon A4 12-inch trimmer is the clear budget standout by sheer customer volume — over 31,000 Amazon ratings at a 4.6 average and a sub-$10 price. Reviewers treat it as a capable light-duty craft and coupon cutter, with the usual caveat that an inexpensive plastic build won't match the durability of metal-railed rotary trimmers.
