Was it Hanna pH meters that have been getting questionable reviews? I found a Hanna pH/TDS/EC meter the other day on Craigslist for like $50, but I didn't call the guy because I thought I heard some bad reviews on Hanna products. Did I goof? Now that I've looked at some similar products online, it seems like it would have been a bargain, at least price-wise.

I'm trying to amass some toys for my trip into the world of hydro, but I have no idea what's reliable and what's not...
