No links, although the use of citric acid as a stop has been discussed on APUG quite a few times.
Is it as good as a branded solution - Somewhat subjective. Plain citric acid stop bath lacks the indicator dye used by the likes of Kodak, and it also lacks any buffering agents. On the plus side, it is dirt cheap, especially if you buy citric acid in bulk.
