Hey guys. I've been looking to add a refractometer to my brewery for a while and was wondering if anyone could tell me what the difference between this one that I found for $25 and the one that the homebrew shops sell for $60. Just to pre-empt the smart@sses out there, yes I know of the $35 difference.
