I got one of the 65$ ones from aquaria.ca - I'm liking it. Sure beats the good ol swing arm hydrometer. Yes its probably not the most accurate - it isn't graduated to the point where 1.024 and 1.0245 are very obviously different - but do we REALLY need that level of accuracy? As long as I can spot the difference between 1.024, 1.025, 1.026 I'm happy.
