I just ordered mast pulpits from www.railmakers.com they are in California, the cost was $725 plus shipping.  We just went with their standard design.  We haven't received them yet, but I will be happy to follow up with a review and pictures once they are installed.  Should only be a couple of weeks!

Got my mast pulpits from Railmakers.com installed this weekend! They feet fit the deck curve perfectly.  Very high quality. They came with attachment brackets so we can add to them in the future for tying things down (not sure what yet).  They also came with the backing plates.  We are very happy with them, here are some pictures.
