Fuel Pump Rebuilder

I have a Carter 3734S fuel pump that I'm planning to use on my convertible after a rebuild. Has anyone used Arthur Gould Rebuilders of NY or Then & Now Automotive(Antique Auto Cellar) of MA? Only a $10 difference in estimated cost between the two.

I sent my 3734S core to Antique Auto Parts Cellar for rebuild. Decision to use them was based on price and website photos. Turnaround just over a week. Cost $75. Looks nice, I'll install this weekend. This one should do until something better comes along.
