I would recommend Belomo also, not very pricy and make sure it is a Triplet which i think all of theirs are. Triplet will ensure the field of view isn't distorted or "fish-eyed" looking. May also check local jewelry stores and jewelry supply stores in the area, one of my jewelry stores gave me a 10x loupe free just for coming in and asking questions about a piece of jewelry i found at a garage sale.
