Water pump to buy?

[37 Coupe]

My biggest question or at least just one of them since buying this 1931 Model A is which water pump to go with. I have studied and studied,some are new ,some are rebuilt some have a bearing on both ends some don't some are dependable some claim to be but can leave you stranded. I think I had it down to one or two it Bratton's but now they say not available.Only thing I know is I want a leakless and a stainless steel shaft.
