I know this is marine chit chat but when I was using RO water for my tropical setup I bought one of the ones in the first link as it was recommended by a couple of the lads at my local MA. Only used the meter about half a dozen times because I changed over to Tanganyikans but I found it to be a good bit of kit, so if you`re interested in buying it for a bit cheaper than the ebay ones give me a shout
