steam pressure switch

On a low pressure residential steam boiler, what would a good choice for a pressure switch? Currently the boiler is 17 years old and only needs to run on about 1psi of steam. The honeywell pa-404b control is set at .5 with a differential of 1. that's the lowest we can set it. Any other control that might work better? Thanks
