Electronic Ph/Conductivity meters

[oscarsi001]

Hey there, So I'm looking at getting one of these and they seem to be either cheap and a bit crap (going by Amazon reveiws) or epensive but Lab Quality ( looking at the Bluelab)
Does anyone on here use them/ have any knowledge (as opposed to 'opinions') about them ????
Ideally looking for something that i can keep on permanently .....
