I don't know about review sites, but I have the cheapo kettle from AIH with 1 welded fitting on it and a boil coil installed. 200 or so batches on it and it has basically been fine. The metal is a bit thin, but the welds look fine. At the time I didn't have the cash to pony up for something nicer, and for 65 bucks (at the time, I think they are 80 now) it has been hard to complain about.
