I have a pair but I think it is against the rule to offer them to you for sale.
I don't know of any new 45s, maybe sophia, but they won't be cheap. the used vintage ones on ebay are cheap and generally in good shape so I recommend buying a few pair. maybe one will be bad and you throw it away but because the price is right, you will be ok in the end. Also a good vintage 45 sounds great.
