We pay $85 each on a 1x purchase, thru the local Fergusson plumbing supply. Totally worth it.

SG reads 1 .100 to 1.400 in 0.01 increments, temp compensation is automatic, F or C scale. Doesn't need to be flushed out after each use to remain accurate and best of all, it's not made of glass. Cheap? No but neither are good batteries. Jim Duncan
