Can't go wrong with the Bluelab truncheon or if you're looking to lighten your wallet, the Combo meter. Their pH pen is meh, if I bought another it would probably just be a Hanna or Milwaukee.
I guess what I'm looking for is something relatively cheap. As long as it lasts a year or two.

My pH pen is an EcoTstr or something, seems ok. Have had that for over year but with little use until now.
I can't really comment on a particular favorite as I have only owned 1. But I have absolutely no issues with it. The Blue lab combo is rather pricey but it's tuff to beat. Not only will it measure pH, it also does temp and TDS.
