I've got a nice Premier chrome over aluminum snare, circa early 70's, but the strainer is worn so it won't hold the snares engaged, it disengages when it wants to. I can fix that with an elastic band to hold the straight lever in place, but I really don't want to do that forever.

Anyone got one that works for a reasonable price? It is the stainer with string holes, not strap clamps. It has the straight lever, not curved one that came a bit later. Thanks.
